Never assume, check ... I stand corrected. I thought the nomenclature of GA11 would have put it later than the FR10 in development terms. I would be even less inclined to loop one at low level like that if that's all the poke it has! Also begs the question of why sailor would want more height/speed in a T8 if it has the same donk as a GA11.
Let's face it, though, this is idle banter and of no relevance to Shoreham. I agree wholeheartedly with sailor that the AAIB will, in the fullness of time, publish the full story. They will also publish the caveats, if any.
