Summary
At the insistence of the Mercury astronauts, an egress hatch affixed with explosive bolts was added to the one-man Mercury capsule to allow a quicker emergency exit from the spacecraft. It was first flown on Virgil I. "Gus" Grissom's "Liberty Bell 7" during the Mercury-Redstone 2 suborbital mission in July 1961, and jettisoned accidentally after landing, resulting in the sinking of the capsule and the near-drowning of the astronaut. All further missions using the hatch had no problems, however.
This particular hatch lacks external shingles and has been modified to carry a micrometeoroid experiment built by Bendix. It never flew in space. In 1973 the NASA Manned Spacecraft Center in Houston transferred it to the Smithsonian.
