And calm descended on the forum..........thanks SP.
Peter-RB: Good morning to you. I think you'll find that just by looking at the pictures of intact RB's - it would seem they were more or less stationary on arrival at the roof.
The river is close by - he didnt even have time to make for that.
However, I don't discount what was said earlier about a relatively successful forced landing, blades are then stopped, then roof caves in.
If I was doing the investigation this morning and looking at the debris - I would be keen to get a very close look at the combiner gearbox........
