Winne the War Baby: Catwalk Misadventure

We were standing on the "catwalk" on the flight deck as they rolled the A3 to the catapult for launch. Per procedure, once the plane was securely attached to the catapult the ? man signaled to the pilot "ready to power", hence the pilot revved the plane to full power. From our vantage point we could see the pilot, but not the ? man. Something wasn't quite ready with the pilot, so he motioned to the ? man to "send a crewman to come check on something", and powered down the A3. We see a crewman hop up onto the wing, and then the body of the plane, as he starts making his way over to the pilot to look in and see what the problem is. The pilot changes his mind and signals out "ready to launch", and revves the plane up again to full power without seeing that the crewman was making his way towards him, and apparently the ? man wasn't aware of his presence either. All of us on the catwalk are screaming and pointing at the crewman on the top of the plane, but nobody could hear us over the sound of the jet! We were horrified as to what was about to happen! Luckily the crewman was quick on his feet and scurried onto the tail and leaped off. Just as hit feet hit the ground that damn plane shot off the flight deck over his head!
