GK121
Irrespective of the model and the fuel each was able to carry, a close relation (Wg Cdr Dickie Martin) who was a TP and in a long and distinguished career (the F-104 was one of over 120 types he had flown) told me that it was the only ac he could remember actually seeing the fuel guage
unwinding when in reheat
.
He said it was as though he had a massive fuel leak; which I suppose was true!
