Re: Korean Air A220 Significant Engine Damage

That is the exhaust section of the engine quite clearly. Last stage of LPT (3rd), with vane segments in front of it. Very unlikely to be the result of FOD damage if its just at the rear of the engine. Even with most ingestion events the debris is normally all but destroyed by the time it gets throu...

Re: Small plane disappears over English Channel

FAA regulations apply but so do EASA regulations and those are even more restrictive.
EASA says that cost-sharing by up to 6 people is deemed an acceptable practice, but when you start posting ads and the purpose is a commercial one, you are toast.
