I'm a little confused re some of the comments. Isn't it the case that the plan was to make a decision at 500ft.. Which didn't happen and ultimately ended 20ft off the top of some trees?? So therefore my maths see that a 10000hour pilot with a 5000 hours co-pilot flying a reasonably sophisticated machine used up 480ft... Now 1000ft doesn't seem that OTT.
In the end you could make the 1000ft, zero but all you are doing is giving those that will take the piss more rope to hang themselves?
