Thanks, Walkabout, I'll read it all.
Something a bit odd about this accident, from what I've seen so far, including watching the video a few times.
I have my own theory but I always prefer to leave the verdict to the official inquiry; however I'm sure the quoted GPS problem is a red herring
Before anyone starts the usual "growling" with hackles raised; although it's been a while, I have a few hundred hours on the type and am reasonably familiar with this type of operation using the Blackhawk, including similar "lights out" ops by night using NVG; I have seen it go badly wrong too (from
very close quarters). Thankfully it wasn't my aircraft and the other crew got away with their error - although a set of new main rotor blades and new trousers all round for those on board (about 20 pairs) were needed
