and nobody has released pics of their turbines
Curious, isn't it?
And those nasty Finns showing innards of their F404s for the whole world to see. Must be a conspiracy at work here.
And the aircraft that did have problems in ash were in thick ash
According to Finns, there they were, flying their Hornets in the severe CAVOK and there were no problems at all. Until the engines where inspected after landing, that is. Issue with prolonged flight in rare ash cloud is not abrasion of the leading edges/transparencies or pitot blockages or engine flameouts. The issue is accumulation of molten and re-solidified ash inside turbines. It won't cause flameout or immediate failure but it will certainly shorten engine's life. That's why the most of the European airforces have taken the stance of cutting all training but maintaining full operational capability: defending the nation or rescuing someone is worth wrecking a few engines. Is having your pax aeroplane sitting for months because you couldn't wait for a couple of days for dust to settle and there are no spare engines to propel it, fair price?
Well, if your life as CEO is short and brutish and if your successor gets to pick up the bill, then the answer is yes. For the aforementioned CEO, anyway.
