But didn't it take something like 5 minutes before the engine started again?
That's not relight lads. That's just weird.
Relight is supposed to instantly (more or less) relight an engine that has suffered flame out. The idea being that the flame will be recovered before the engine spools down below a critical level. If the engine has stopped altogether (as it must have in this video) then all the cracking ignitor plugs on the planet won't get it going again. You need it to turn first......
