Iron City,
One chap at BA was doing a Top Temp and Speed Control trim on a VC10 at Heathrow when he was sucked out from under the engine and into the intake. The amplifier is only about three feet back from the intake lip. He was quite badly injured - lost a thumb and some fingers and punctured an ear drum - but a man going into the intake causes a compressor stall and is blown straight back out again. Its a long way down from a VC10 intake.
Having done a few TT&SC adjustments on the Conway in my time I'm quite familiar with its sucking power at 103% RPM. It sure does suck! Makes the old cojones vibrate a bit too!
