Many years ago a BCal 747 taxied before awaiting clearance from the two engineers carrying out the pushback. The two engineers had to dive to the ground and hang on to each other as the no.2 engine passed over their heads!
No fault of their own, they were severly shaken, however the 747 capt was, I believe dismissed.
Some years later a colleague of mine was almost run over by the left prop of an ATP, again the Captain failed to wait for the all clear from the ground engineer before taxying.
There are many ways to get sucked into an engine. The details of this 737 case will (I hope) be a warning to us all!
