I remember years ago pushing back a DHL B727 bound for Helsinki on the "old" cargo apron, stand 31 I believe
The Captain advised that it would be a "wet" start......we pushed him back about 50m or so from the white/red wall and little did I know there would be a huge flame shoot out of the engine and head directly towards the Police chopper.
The copper chopper captain went into a right tizzy!! He gave me and my headset guy a proper rollicking!! He claimed the flame went over him, think he exaggerated somewhat but it was a great sight!!
Happy Days
