OK.... I'll try to make this as short as possible....
I was a mechanic for Air Midwest. The day the space shuttle blew up in '86 I must have watched it over and over a hundred times (I worked the graveyard shift). So I'm already spooked.
So.... I walk into the hangar that night and the foreman tells me to go with another mechanic, we're flying out to retrieve a plane out in the system. The door won't shut and lock.
I'm a junior mechanic going out with a senior. Along with his tools, senior grabs a few rolls of duct tape and out we go in the Navajo.
We get to the plane and sure enough. Door ain't locking right.
We close the door as best we can and wrap the door and fuselage with all the duct tape. But he and the pilot are concerned about pressure differential blowing the door open on ascent. Which, as you can see in the pic below, would have taken the engine out.
I'm in a seat over the wing with the escape hatch sitting in my lap. Senior is sitting on his backside holding the door latch with his feet on both sides of the door.
We get to altitude. Pilot gives the thumbs up. I put the escape hatch back in. And senior relaxes.
And that's how it was done.
