Mid-flight deaths are rare and airlines are legally required to report them publicly. The allegation was aired Monday on “The Stew Peters Show” podcast.

“All of these allegations are false,” said Delta. “The pandemic has been an incredibly tragic time for many, and our hearts go out to the hundreds of thousands of families of those who have passed away from the horrific virus.”

The story came from Peters’ podcast guest, Jane Ruby, who said she had been told about it by three “whistleblowers directly related to Delta Air Lines,” one of whom she said was a flight attendant on the flight.

She said that the co-pilot on the flight was safely able to land the plane, and that the flight had occurred within the previous 10 days. She also said the people shared with her a number of stories about other vaccinated Delta staff’s deaths and health problems.
