Good to read that no-one was seriously hurt (or worse).
I guess many of us think about fuel issues when we read
of such events shortly after takeoff.
It's been a while since I flew a Cherokee Six, but I recall a great
deal of time spent in training on the fuel system - the precept being that it was easy to balls up so better get it right.
Obviously unclear at this stage what the outcome of any investigation into this event will be, but it does appear it certainly had some fuel on board, given the fireball. However I will be interested to see if there were any problems around the supply control...
FP.
