Bruce absolutely, a boroscope inspection would be more detailed to a point.
But look who is doing the inspection, an entity (BA) who wants to get flying.
Its like this,
Imagine you killed someone and being a judge, you had to convict yourself, would you?
BA wants to fly, of course we all want to fly, but from I can understand of the situation, there are no IMPARTIAL inspections taking place.
The only people keeping it together, are Eurocontrol and the likes.
I just hope they don't back down for the wrong reasons.
What we need are wind changes etc and that volcano to stop belching out this material into the air.
PENKO: your comment about reduced take off etc. Big Difference, there isn't bits of glass melting in the combustion chamber and choking the engine. CAVOK? can you see ash travelling at 800 km/h.
