when report shows jets CAN'T handle storms: Pilot ejected due to 'bad weather' before jet 'flipped', flew 100ft above trees in 'zombie mode' and crashed in field

A F-35 jet could have crashed on Sunday due to poor weather in South Carolina, new audio suggests - as questions mount as to why the disastrous training exercise was allowed to proceed.

The F-35B Lightning II which the unnamed Marine pilot was flying is believed to be at risk of malfunctions if it flies in thunderstorms, according to a Forbes investigation in November.

Its sister jet, the F-35A, is more severely affected and cannot fly within 25 miles of lightning.

The issue lies within the F-35's OBIGGS (Onboard Inert Gas Generation) system, which pumps nitrogen-enriched air into its fuel tanks to inert them, preventing the aircraft from exploding if it is struck by lightning.

'F-35B and C variants have some of the same OBIGGS issues as the F-35A, but have been able to alleviate operational impacts,' said Chief Petty Officer Matthew Olay, spokesman for the F-35 Joint Program Office, in an email to Forbes last year.

Audio from Sunday's crash shows the pilot telling emergency responders, after ejecting, that he 'lost it in the weather'.

Mike Rivero: It's been known for a long time the F-35 has to avoid lightning! And it cost how much?
