Black Box Data Reveals Secret Audio From Biffle Family Plane; Recording Made Days Before Crash Raises Alarming Questions
Investigators analyzing flight data from the black box of the Biffle family’s aircraft have uncovered a previously unknown audio recording—one that authorities say could dramatically reshape the timeline and understanding of the fatal crash.
According to officials familiar with the investigation, the recording was captured three days before the plane went down and features Greg Biffle speaking privately with his wife. The existence of the audio was not disclosed in any flight logs or maintenance records and was only discovered during an advanced forensic extraction of the cockpit voice recorder.
A Hidden Recording
Sources say the audio was not part of standard cockpit communications. Instead, it appears to have been stored in a secondary buffer within the recording system—possibly triggered during a ground test or powered avionics check while the aircraft was parked.
In the recording, Biffle can be heard telling his wife that he was increasingly worried about the aircraft and “something that didn’t feel right,” according to two officials who have reviewed the file. While investigators have not released the full transcript, they confirmed the conversation referenced a concern that had not been reported to mechanics or aviation authorities at the time.
“This was not casual conversation,” said one source. “It suggests foreknowledge of a potential risk that investigators were previously unaware of.”
Investigation Takes a New Turn
Until now, authorities had focused on mechanical failure or an unexpected in-flight emergency as the most likely cause of the crash. The newly discovered recording has prompted investigators to widen the scope of the probe to include decision-making in the days leading up to the flight.
As a result, officials have begun:
-
Re-reviewing maintenance and inspection records
-
Re-interviewing ground crew and service technicians
-
Examining whether the aircraft was flown despite unresolved concerns
Aviation experts note that pre-crash awareness—if confirmed—can be a critical factor in determining responsibility and causation.
“When there’s evidence a pilot or owner suspected a problem beforehand, it changes how the entire case is evaluated,” said a former federal air safety investigator. “It doesn’t mean fault—but it demands deeper scrutiny.”
Family and Authorities Respond
Family members declined to comment on the specific contents of the recording but confirmed they were informed of its discovery earlier this week. In a brief statement, a family spokesperson said they are “cooperating fully” and are seeking “clear, factual answers.”
Authorities stressed that the investigation remains ongoing and cautioned against drawing conclusions until the audio is fully authenticated and placed in context with other evidence.
Still, officials acknowledged the recording is significant.
“This is not evidence we can ignore,” an investigator said. “It forces us to reexamine what was known—and when.”
Investigators are expected to release additional details after forensic analysis of the audio is completed and legal reviews determine what portions can be made public. For now, the secret recording has introduced a troubling new dimension to a case that continues to raise more questions than answers.
