Interesting quote re the fuel load.
I flew the first ever Police T1's in Europe. They were fantastic ships with stacks of power and a fuel load of Maximum: 2.5hrs. I also flew the first semi glass panel "P1" Bond cab all those years ago and its fuel load was just around 2hrs. Today as the years have passed they have become fatter and heavier payloads and the lates P2++ I would suggest carries fuel for no longer than perhaps 1.5hrs (I stand to be corrected by any of the operators).
What version is the Strathclyde 135?
2hrs airborne before the crash, to me seems to bring it very very close to its minimum fuel?
