Summer, 1972. Don’t recall any stories about aircraft inside: I was more interested in the stories about what they found in the sides (not bottom!) of the crater.
I had to look it up, because I couldn't remember the details...
Standing on the crater's 150-foot-tall rim, Mark points to a piece of wreckage that has been on the crater's floor since the late 1960s. He tells a story that suggests that the world has more to fear from people flying small planes than rocks falling from outer space.
"Two guys in a single-engine Cessna decided to fly into the crater to get a closer look," he explains. "But when they got in, they couldn't get out. There's a layer of wind spins over the crater like an invisible force field. Two and a half hours later, they ran out of gas and tried to land, but the plane cartwheeled and crashed. They were lucky, they lived."
And, what was found in the sides of the crater?
Several expeditions had been drilling “straight down” the center of the crater - to try to find the meteor rements dy sample drilling and vertical mining. (Like a gold mine or silver mine.)
Finally, after many years of failures, one person was shooting bullets into the mud around his campfire, and realized that even a low angle shot made a round hole. Then he looked back at the crater waal and found one side pushed up more than the ohers, tried drilling sideways into the wall under the high spot, and immediately found many fragments.
Don’t know if they ever got the whole rock.
