Okay, Copenhagen Suborbitals had an engine test, which generated some
rather spectacular video

First you see the test (all 17 seconds) in real time, then
repeated at 240 fps. Apparently those GoPro Heros really hold up ....


Y'think GoPro will warranty that 'un?


Then comes the post mortem:

Seems there were a few welds on the nozzle cooling jacket which
did not get full penetration.


I wonder if one of the engineers produced that one. Otherwise, they
need to use a certified weldor from now on. If they did, the guy
needs to practice a LOT and be recertified post haste.


Interesting, to me, is the robustness of the electronic components
- at least the flash memory chip is expected to provide usable data,
once disconnected from the burnt board mounted on a working board.


Methinks they're probably too optimistic.
