After the crash of the Cessna 550 Citation II that claimed the life of former NASCAR driver Greg Biffle and his family, the National Transportation Safety Board (NTSB) launched an investigation. It goes without saying that well-wishers of the Biffle family want to know what took place, but there is a particularly jarring detail that they need confirmation on.

As reported by PEOPLE, Cristina Grossu Biffle, 35, texted her mother, Cathy Grossu, right before her death on December 18. She wrote: “We’re in trouble.” The website claimed it was Cathy Grossu who spoke to them. Since then, the media has been waiting for the NTSB to comment on this piece of harrowing information.

The press raised this question during a conference by the NTSB. Answering the question, the spokesperson, Michael Graham, stated: “At this time, we are not aware of that. If somebody is aware of a text or anything like that, please make us aware of it. Let us know via email, and then we will contact you.”

The crash happened shortly after takeoff. The plane is understood to have declared an emergency and was returning to the Statesville Regional Airport for landing.

It crashed just 10 minutes after takeoff.

The investigation is currently in its initial stage. The data from the cockpit voice recorder and the flight data recorder can take around a week to be processed and interpreted, after which a preliminary report is expected to be prepared.

The crash was terrifying. At first, it was unclear what exactly happened as the plane returned for the landing, but the NTSB has shed some light on the same.

What the NTSB knows about the crash

As per reports, the aircraft took off at around 10:05 AM ET from runway 28 at Statesville Regional Airport. It initially made a left turn west before taking another left turn east towards the airport. It flew a left base turn to runway 28.

After that, the initial point of impact is said to be a runway light stanchion, which was located 1800 ft from the runway threshold. The airplane then impacted trees, two other light stanchions, and the airport perimeter fence. Minutes later, the plane came to a stop near the runway threshold.

As per NASCAR journalist Steven Taranto’s report: “All four corners of the airplane as well as flight control surfaces have been identified in the wreckage/debris field, and both engines were present with the main wreckage. The majority of the fuselage and inboard wing sections were consumed by the post-impact fire.”

The crash claimed the lives of all the people on board, including Greg Biffle, his wife Cristina, and both children, Ryder and Emma.

Biffle was a beloved figure in the sport. Apart from his competitiveness on the track, the fans loved him for his humanitarian work. He was also a trained and licensed pilot. However, he wasn’t licensed to fly the Cessna Citation II that he was on.

There have been questions about whether he was with the pilot in the cockpit during the emergency. However, like many other questions, this remains to be answered after the investigation.
