Not at all Nick. Fair question and I perhaps should have specified what I meant by assualt - I dont think thats giving too much away. I mean "assault" as in the fast-rope delivery of special forces troops for tactical reasons to a potentially hostile target. Thus the very fast approach, late flare to a hover over the target. It's my belief (with no certainty, but some background) that whatever has (obviously) gone so sadly wrong has occured in this unforgiving flight regime. I have my beliefs about what may have caused the heavy contact with the deck but think I'll keep those to myself, as I will about the profiles used for such ops.
