Lightning ROC
I have seen a signed certificate (from the TP who flew the aircraft) suggesting that a Lightning F1 went from brakes off to 36000 in approx. 3 min 30s.
Whilst regaling this tale to a party of visitors at a well known aviation museum, one of them piped up along the lines of 'yes, but that's in dry power, in full reheat its more like 90s'.
When acknowledging the gentleman's contribution to the tour, I asked him how he knew those figures.
'Because I did it myself in that aircraft'.
Horses mouth then.
