Four States and the Grand Canyon

Thanks Dave. The flight was a lot of fun.

Yes, I use an oxygen system made by Nelson. I think they're out of business
now.

There are no flight plan requirements based on altitude.

I mostly use a World Aeronautical Chart but just this summer bought a GPS to
record a track of my flight.

Amazing trek! As a propeller-head with only a few (albeit very
enjoyable) glider flights I had a few questions...

- For these high flights (you mentioned 17k) are you using some sort
of oxygen system?

- Isn't there a certain altitude that requires a flight plan?

- What sort of equipment do you use for these XC flights (transponder,
gps, etc)?
