I've done the Hypoxia course at North Luffenham (before the move to Henlow - I'm an old fart these days) and its a real eye opener.
Its the one thing the CAA should mandate and scrap the pointless box ticking days where you 're-learn' how to point a fire extinguisher or open a door.
I felt I was fine. The others were being effected. Look at him - its like he's had 7 Stellas! I'm fine. Why isn't it effecting me? I must have brilliant lungs! My god I'm the best they've ever seen!

The counting backwards in 3's from 117 stopped at above 60 and started going up, then down, then down again in 2's then in 8's. My attempts to draw an elephant tailed off into a scribble then constant figures of eight.
Its very, very, dangerous.
Its very, very possible.
Its very, very casually treated.
