Questions & Answers
Q: How did Grissom escape from Liberty Bell 7 after the hatch blew off?
Grissom quickly unbuckled his harness, removed his helmet, and hoisted himself out of the capsule through the open hatch. He then swam free while his spacesuit filled with water.
Q: What were the two main theories behind the cause of the hatch detonation?
One theory suggests that the emergency release lanyard became tangled in the parachute shrouds, triggering the hatch when the parachute collapsed. The other theory blames static electricity from the recovery helicopter, coinciding with the moment the helicopter crew touched the capsule.
Q: Was Grissom blamed for the incident?
