Cafesolo, no doubt most, if not all of the aircraft you were involved with were powered by AVGAS, not the far less flammable JetA1 of today. I'm not in a position to check the regs, but I do know that when I took my professional licence exams, the rules said acceptable for JetA1, not so for AVGAS.
These days, turbine powered helicopters are even allowed to carry out rotors running refuels, subject to suitable precautions being taken.
