Some good news

I had my first wave flight early October. I
stopped at 18000 as that was as high as
you can be with a cannula. Then poked
around between the Alberta Livingstons
and Porkies between 9000 and 15000 for
a couple more hours.

The post 18000 part of the flight I had set
the flow for 15000, but after landing I was
so wiped out I had to take a couple days
off from flying.

Folks, especially us older guys, living in
low elevations need acclimation to the
10,000' level O2 systems are set up for.

In the meantime, you lose significant IQ
points and your decision making will not
be as good as when in your armchair at
home.

Hanging yourself on the chest strap by realeasing the leg straps has been done unfortunately. Another parachute question were the leg straps off or is it possible the friction buckles were misrouted(or less likely failed) and they were on but legstraps fully extended? Route through the friction buckles backwards(slack legstrap will be on the inside) and it looks normal at the buckle but won't hold.
