Aha
That explains it. Didn't know it was possible. Good to know if I have said some stupid things and want to deny it....
Basically all twin-engined aircraft becomes more tricky to operate (and land) if one of the engines quit, but I doubt the Llghtning would become uncontrollable, and being at around 25000 ft the pilot should have had ample time to correct and adjust his flying.
No finger pointing from my side. As long as I don't know exactly what happened, this is just a reflection on my part.
