[PSUBS-MAILIST] onboard gear

[Alan via Personal_Submersibles]

Jon,
I will add to that; designing & maintaining a sub that is entanglement free.
Alec hit a cable & was catapulted backward, the R300 got caught on a rope
& my ambient on it's first pool test got caught on a rope before it went 10ft.

It's not just the R300 that doesn't have room to carry the gaseous equipment for such escape, it's almost certainly the vast majority of K-subs and those based off the Kittredge design.  That's why taking this activity seriously, fabricating to standards, testing to standards, peer review by fellow submariners, maintenance and safety plans is so important.  Our greatest and most dependable safety plan is a vessel that survives diving parameters and returns to the surface every time.  That reduces risk to issues such as entanglement that might necessitate escape, however like all extreme activities I think it is axiomatic that ours is not without risk.
