I finally have some footage to show. :)
The Video is filmed at 90 frames per second, but played at 24 frames per second. so Slo-mo.
Skip ahead to 14:49 10 sec before the 2.6 endcap fails. The estimated depth is 147m! Nice!
The Next point skip to is 19:52. At 180m, the 1/2" endcap made from 2 x 1/4" disks fails 10 seconds from that point.(at 20:02) If you watch closely you will see the face seal being forced out just before the implosion.
