Decades after the Liberty Bell hatch incident, Rick Boos finally gets to examine the restored space capsule. He studied and argued for years that Grissom did not blow the hatch intentionally or accidentally. As it turns out, in an interview he conducted with Jim Lewis who was on the recovery team helicopter, Mr. Boos was told that the likely source was a static discharge between the helicopter and the capsule, thus actuating an explosive device that tossed the hatch into the ocean. Liberty Bell sank to a level 15,000 feet below sea level before it was recovered 38 years later in 1999.
