The estates of two pilots killed alongside former NASCAR driver Greg Biffle have filed wrongful death lawsuits seeking a combined $15m each in damages over December’s fatal plane crash in North Carolina.

Dennis Dutton and his son Jack died alongside the 55-year-old racing star, his wife Cristina, and their two children when their Cessna 500 Citation II crashed on 18 December.

The aircraft went down shortly after takeoff from Statesville Regional Airport, bursting into flames about a third of a mile from the runway.

Legal filings submitted earlier this week allege the motorsport champion, who owned the jet, failed to ensure his aircraft was properly maintained.

Maintenance and cockpit experience questioned

A preliminary investigation previously revealed the plane’s altimeter was providing incorrect readings prior to the fatal descent.

It also indicated that the elder pilot had handed control over to his son shortly before the tragic impact.

The National Transportation Safety Board (NTSB) noted the younger aviator was seated in the copilot position at the time of the accident.

Crucially, neither the son nor the former stock car racer possessed the required endorsements on their pilot licenses to serve as a copilot for that specific aircraft type.

Awaiting final investigation findings

Former aviation safety consultant Jeff Guzzetti believes this lack of an experienced copilot may have been a critical factor in the disaster.

The NTSB continues its thorough investigation into the incident and has not yet published a conclusive final report.

The driver involved was a highly decorated figure in American motorsport, securing more than 50 victories across the sport’s three national divisions.

A celebrated racing career

He claimed the Truck Series championship in 2000 before adding the Xfinity Series title to his resume two years later.

During his peak years, the veteran competitor accumulated 19 wins at the premier Cup Series level.

Beyond the track, he was recently honoured for his humanitarian work following Hurricane Helene.

The former champion used his personal helicopter to deliver essential aid to flooded and isolated communities in western North Carolina late last year.

Formula 1 faces the threat of a third consecutive race cancellation as severe weather and strict United States safety laws jeopardize Sunday’s Miami Grand Prix.

The sport returns this weekend following an unexpected five-week break prompted by the cancellation of both the Bahrain and Saudi Arabian rounds.

However, heavy rain and potential thunderstorms threaten to disrupt the highly anticipated 2026 event at the Miami International Autodrome.

Forecasters currently predict an 88% chance of rainfall during the race, accompanied by a 53% probability of lightning strikes.

Strict safety protocols risk race suspension

These ominous weather conditions have placed teams, drivers and the governing body on high alert ahead of the weekend.

Unlike many other host nations, US legislation mandates that outdoor public events must be halted if thunderstorms approach and pose a lightning risk.

Such treacherous conditions would inevitably ground the mandatory medical helicopter and force a complete evacuation of all spectators from the venue.

Should thunderstorms materialise, race officials will display the red flag and immediately recall all cars to their respective garages.

FIA regulations dictate clear restart procedures

The sport’s governing body previously reminded competitors that stewards possess the authority to suspend sessions to allow personnel to seek shelter safely.

Under Article 57 of the sporting regulations, a red-flag scenario requires all vehicles to stop in the fast lane before being wheeled inside.

Florida is notoriously susceptible to unpredictable and intense weather fluctuations, though current projections suggest dry running across Friday and Saturday.

If the grand prix is suspended, the race director must publish a new restart order at least 18 minutes before action can resume on track.

Max Verstappen has given his full blessing to race engineer Gianpiero Lambiase’s upcoming departure from Red Bull to McLaren, insisting he would be an “idiot” to block the career move.

Red Bull confirmed earlier this month that their highly rated technical specialist will leave the team when his current contract expires in 2028.

The announcement arrived shortly after it emerged the engineer had decided to pursue a fresh opportunity with their Formula 1 rivals.

A significant shift in stance

The three-time world champion had previously indicated he would have no appetite for racing if his trusted confidant was no longer communicating over the team radio.

Following his maiden title triumph in 2021, the Dutchman famously declared that he would retire from the sport as soon as his engineer stepped away.

However, the 27-year-old has significantly mellowed his position and acknowledges that circumstances have evolved since that initial declaration.

“I will have to work with someone else, but I think times change, and the offer that he got, I would be an idiot to try and keep him,” Verstappen told reporters.

Looking toward the future

Lambiase has been a valued member of the reigning constructors’ champions since joining in 2015, forging a famously direct working relationship with his driver.

McLaren have already praised their future signing as a top talent, while Red Bull remain committed to securing further championships before the eventual separation.

The current championship leader stressed that an open dialogue within the team made processing the transition incredibly straightforward.

“It’s not only about me all the time, it is also about his career and moving forward, so for me, it was a no-brainer to be honest,” he explained.

Long-term commitment unaffected

The Red Bull star noted that the pair maintain an honest relationship and that there are absolutely no hard feelings regarding the transfer.

When questioned on whether this high-profile technical departure impacts his own long-term future with his current employers, the driver was unequivocal.

“It has got nothing to do with it,” Verstappen stated firmly.

George Russell has dismissed the significance of Mercedes team-mate Kimi Antonelli’s early Formula 1 championship lead ahead of this weekend’s Miami Grand Prix.

The 19-year-old Italian currently holds a nine-point advantage over his British counterpart heading into the fourth round of the 2026 season.

Antonelli recently became the youngest championship leader in the sport’s history and is chasing a hat-trick of race victories in Florida.

However, Russell insists the internal dynamic at the Silver Arrows remains unchanged despite his younger colleague’s impressive sophomore campaign.

Marathon mindset for Mercedes

The 28-year-old driver compared the grueling length of the modern Formula 1 calendar to the London Marathon when questioned about the current standings.

“The guy who’s running the London Marathon, after three miles, you’re not thinking about the finish line, because you’ve got 23 miles to go.”

Russell was eager to point out that the championship battle is still in its absolute infancy.

“We’re in race four, so it’s not even a consideration, although of course he’s done an amazing job so far this year.”

The former Williams racer suffered misfortune in the previous round but pointed to solid recovery drives, including a second-place finish in China and a fourth-place result in Japan.

Development race heats up

The British driver remains confident that a smooth weekend will yield a race victory very soon.

“You’re always going to have these difficult weekends, but I hope every difficult weekend results in either P2 or P4.”

Meanwhile, the Brackley-based squad are taking a distinctly different approach to car upgrades following a five-week break in the calendar.

While rivals Ferrari, McLaren and Red Bull have brought major new parts to the United States, Mercedes will split their crucial developments across the upcoming double-header.

Lewis Hamilton has declared himself “fired up” for the resumption of the 2026 Formula 1 season as Ferrari aim to close the performance gap to championship leaders Mercedes at the Miami Grand Prix.

The seven-time world champion returns to the track this weekend following an enforced April break.

Ferrari currently sit second in the Constructors’ Championship, trailing their Brackley-based rivals.

Hamilton and team-mate Charles Leclerc occupy fourth and third respectively in the drivers’ standings, behind the Mercedes duo of Kimi Antonelli and George Russell.

A tall order to catch the Silver Arrows

The Italian marquee had shown promising signs during the opening three races of the new regulatory era.

However, the British veteran acknowledges the immense challenge of overhauling the current pace-setters.

Hamilton believes his team is facing a power deficit compared to both Mercedes and the new Red Bull-Ford power unit.

“Everyone’s had more of an intense time to work on refining the car,” said Hamilton.

“Just feel fired up for the second stab at it.”

Upgrades crucial for development race

Most teams are expected to introduce significant aerodynamic upgrades when practice begins in Florida on Friday.

The Scuderia are also banking on potential engine development opportunities in the upcoming additional upgrade window.

Despite acknowledging the factory’s relentless effort during the spring break, the former Mercedes driver remains realistic about the speed of progress.

“I’m really grateful for all the hard work. I’ve been back at the factory every week during this break and seeing how hard the team has been working in bringing an upgrade,” he explained.

“To close that gap, that means we have to do double that development each time of others, which is a really tall order.”

“You have to assume everyone’s developing at a similar sort of rate because it’s new rules, so if a team brings a tenth, we need to bring two.”

Max Verstappen says he is in no rush to decide his Formula 1 future as the Red Bull driver evaluates his options ahead of this weekend’s Miami Grand Prix.

The Dutchman recently suggested he could walk away from the sport following a highly frustrating start to the 2026 season.

Sweeping new regulation changes have severely hampered Red Bull’s performance, leaving the reigning constructors’ champions fighting an unfamiliar midfield battle.

However, speaking before the race in Florida, the defending world champion insisted there is no immediate update on his racing plans.

“I still have time and I’m taking my time,” he said.

Engineer departure will not dictate future

Speculation regarding a potential exit intensified following the shock announcement that his long-time race engineer, Gianpiero Lambiase, will join McLaren by 2028.

Lambiase has guided the 28-year-old through every race since 2016, prompting past claims from the driver that he would quit if they were ever separated.

Despite those previous assertions, the Dutch racer clarified that his colleague’s impending switch has no bearing on his own career trajectory.

“We have a very honest and open relationship, so that was all good,” he explained.

“I wish him all the best and for me there was no hard feelings on that.”

Red Bull search for performance

Red Bull have introduced significant car upgrades for the Miami weekend in a desperate bid to close the gap to their rivals.

The Milton Keynes-based outfit have struggled to adapt to the new 2026 ruleset, falling noticeably behind the leading pack.

“We are a little bit further behind at the moment than what we had last year,” Verstappen conceded.

“I just hope that we can escape a little bit that midfield battle, and we can be actually a bit further up front.”

Formula 1 will resume its 2026 season at the Miami Grand Prix this weekend following an enforced April break, with organisers completing a rapid transformation of the Hard Rock Stadium.

The sport returns to action in Florida after the unexpected cancellation of both the Bahrain and Saudi Arabian Grands Prix earlier this month.

A 3.36-mile, 19-corner temporary street circuit has been constructed around the permanent home of the NFL’s Miami Dolphins.

Delivering an impossible turnaround

The 265-acre site in Miami Gardens requires the complex installation of approximately 250 temporary structures to meet top-tier motorsport standards.

This massive logistical effort takes place just four weeks after the venue hosted the prestigious Miami Open tennis tournament.

The multi-purpose stadium is also scheduled to host seven matches during this summer’s football World Cup in just seven weeks’ time.

Miami GP president Katharina Nowak acknowledged the heightened external focus on the fifth edition of the race following the sport’s sudden hiatus.

“We definitely don’t change our planning as we started planning back in the summer of 2025 for 2026, so we’re right where we needed to be, but I think the anticipation definitely grows for the race.”

Heightened anticipation for racing return

The event chief noted that the four-week absence of competitive action has generated significant excitement within the wider motorsport industry.

“I’ve gotten a lot of clues or hints from people in the industry that there’s a lot of excitement around Miami, which we, of course, embrace and are excited to hopefully continue to deliver an excellent event.”

The Sunshine State showcase marks the first of three scheduled stops in the United States on the current racing calendar.

Uniquely, the inside of the 65,000-seater stadium is utilised to house the team hospitality units and media facilities directly on the pitch.

Max Verstappen’s decision regarding his Formula 1 future will not be influenced by the upcoming departure of his long-time race engineer Gianpiero Lambiase to McLaren, according to team principal Laurent Mekies.

Lambiase has worked alongside the Dutchman since he joined the Milton Keynes-based outfit in May 2016.

The highly respected engineer is scheduled to leave the reigning constructors’ champions to become McLaren’s chief racing officer by 2028 at the latest.

Mekies firmly dismissed suggestions that losing such a close ally would factor into the three-time world champion’s career plans.

Team dynamics and engine frustrations

The team executive emphasised the driver’s deep understanding of the sport and internal staff structures.

“Obviously, we speak with Max every day. And Max knows motorsport upside down.”

Mekies added that the 26-year-old lives and breathes the team environment and understands the natural turnover of successful personnel.

A more pressing concern for the championship leader has been his dissatisfaction with the behaviour of this year’s newly introduced hybrid power units.

The current regulations mandate a near equal split between internal combustion and electrical power, significantly altering the driving experience.

Miami Grand Prix rule adjustments

Minor regulatory changes have been introduced for this weekend’s Miami Grand Prix to address some immediate driver concerns.

These tweaks aim to allow flatter-out driving during qualifying sessions and reduce dangerous closing speeds between harvesting and deploying cars.

While acknowledging these changes will not alter the overall pecking order, Mekies welcomed the move as a positive step forward.

“Nobody pretends it’s going to fix everything, but it’s a good step, and we will certainly support more steps in the future so that the drivers can be flat-out out there.”

Push for long-term hardware changes

Looking further ahead, there is growing consensus among team bosses that more fundamental engineering adjustments are required.

Mekies expressed agreement with McLaren team principal Andrea Stella regarding the necessity of long-term hardware changes to the power units.

Stella has advocated for adjusting the power ratio to place less compromise on chassis design and overall drivability.

“There should be a consideration for some hardware changes, more for the longer term.”

High-level discussions are reportedly already under way among motorsport executives to address this fundamental issue.

The primary proposal under consideration would increase the internal combustion engine’s fuel-flow rate, shifting the power delivery ratio closer to 60:40 for next season.
