Did he get the badge leg?

This is even worse than the guy who wanted to kludge together an aviation 02 kit from medical 02 equipment.
A good number of ears ago, I attended a wave camp in Petersburg, WV. The wave was strong but it was getting late in the day and a guy in a 1-26 was overdue. We reached him on the radio and his responses were incoherent - he was obviously 'out of it'. We coached him back down and the reason for his hypoxia was quickly found: he had used a cheap hospital mask (w/o re-breather bag!) tied to his A8A. He said he consistently readjusted the flow meter according to the altitude he was in. However, due to the cold conditions, the material of the mask shrunk and the hose coming from the regulator simply fell off the barbed nipple! He even had one of these 'red-green' indicators in the line but never checked if the O2 was actually getting to his mask. The barogram revealed that he was at over 26k ft (never mind that the wave window was only good for 23k ft!) and he had no recollection of ever going above 20k ft!
I hope that fellow thought twice about using his cobbled-together O2 system again!
