I have seen the one with the guy being sucked down the intake on the carrier.Glad he was OK.That clip is now used as part of the ramps safty course at STN.A couple of months back one of the Ryanair Engineers last half an arm down a JT8.Due to this our company has stopped us doing manual starts on our 737.When I was an apprentice at BAe Hatfield one of the flight test guys was sucked into one of the engines during a full power run.After that engine guards were used.I must admit to having lost most of my fear for jet engines and find myself getting more worried about other people working around them when i'm doing the engine runs.
