Back end flameout roasts F-35 on runway 25 Sep 2016 Richard Chirgwin
"...The fire happened while the pilot was starting the F-35; the pilot exited the aircraft while it was extinguished, and the US Air Force reports there were no injuries.
While the cause of the fire is still under investigation, Aviation Week says “initial assessments point to a tailpipe fire due to strong tailwinds as the engine was starting”.
If accurate, that would point to an aborted start that left too much unburned fuel in the exhaust duct. Aviation Week says at the time, winds were gusting up to 70 km/h (45 mph) from the northwest to west-by-northwest....”
