Hell, if this were a QF flight, we would be up to page 4 already.
I heard that Qantas had an engine fire up near Singapore a few weeks back. Not in the papers though.
It is believed the fire was caused by residual fuel in the planes tail pipe.
I have seen this occur a number of times on start up but unless I have lost some technical knowledge, I can't see residual fuel causing a 3 second fire at altitude.
