Quote:"Let me get this straight: failures on all four engines and a 25,000+ feet drop isn't worrying to you? I mean, sure, that's ok if you're at FL410, but maybe not at, say, FL240?"
The point I was trying to make that there's a big difference between flying through a dense cloud of volcanic ash (like the BA) and flying through wat we have over Europe at the moment.
The point relating to BA's engines was that even them restarted so flying through European airspace at this moment poses no immidiate threat to the engines!!!!!
I am repeating myself but , Yes at the longer run it could mean highger maintenance cost and even a very thin layer off anything building up on turbineblades will be picked up by health monitoring.
And yes I would be worried if it would cause engines to stall and quit during flight.
