What is not being mentioned is that the 72 was being flown much as one might fly the 42. In terms of handling, they are chalk and cheese.
I'd have had no problems with that horizontal profile in the 42, but with this aircraft, with the load we see, I'd have insisted on a good length stabilized approach.
With plenty of height and the nose comfortably pitched down a tad, this profile was doable, despite being not acceptable in principle. However, what I see is quite the opposite - a totally unacceptable flight profile for a 72 at that guessed weight. Now tankering fuel is being mooted.
Going back to my former post and the puff of grey smoke behind the port engine. Is there any reason to believe the fuel may have been contaminated?
