What is the world record for the longest freefall time without the use of oxygen?

You could be talking about a number of different things:

- Highest jump without oxygen was from around 32k by Patrick DeGuiardon with a funny looking bullet-like helmet.

-Longest time-in-freefall without Oxygen? Mike Maschef (Grey Mike) at Z-hills has flown 5 minutes and 45 seconds from 22k in a wingsuit at Z-hills.

In the tunnel or out of an airplane?
And do they have to have lived?

There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence. (tbrown)

I thought I read somewhere about a guy who jumped from over 40k feet without oxygen...but he did breathe O2 on the way up. Sorry no source

Who keeps these records?

If the plane is unrecoverable then exiting is a very very good idea.

What I'm wondering about is the longest freefall time without the use of any suplimental oxygen.

For example, when someone uses no suplemental oxygen immediately prior to take off, on the flight, or during the actual freefall, and not the height record, but the duration of flight with no parachute or drogue deployed.
