Wow is all I can say! First off, I'm amazed that anything could have flown in that state, second it says something for how tough the S76 is, third it's amazing that the crew apparently felt no vibrations and obviously didn't have a look around their cab after landing if they really didn't make an entry in the journey log
I'd have to agree with you SAS, that in any years flying I've never seen anything like that - which survived!
