Unusual to see a big block on an RV, but I'm sure it has been done.

Harmon Rocket is pretty much that. (And the best versions can really go.) http://www.harmonrocket.com/

I'd think someone who works at NTSP would take care to minimize risk, so probably wasn't too risky for a test flight...

Once again, the imaginary cannula regulation rears its head :ahhh:

Technically, wouldn't the pilot just need to set a decent down to 10,000 feet...

In some places, you won't make it to 10K before SPLAT. I think the jets which have this feature do a 90 degree turn and descend and level off at 15K.

What, no automatic chute? :-)

I think George B. has spent time contemplating this matter. George? What say you?

I'm pleased that he was wearing a pulse oximeter. From his comment, it is unclear
if he was wearing a cannula, mask or pressure breathing mask.

Me? Given the whole O2 partial-pressure thing, I would not do >20k MSL without a
pressure breathing mask and pulse oximeter. Losing the pulse oximeter due to cold
soak would be reason enough for me to begin a "sporty" descent.

I did my high alt check/sign-off in a B737-800 sim. As I recall, SOP was:

- Don the mask & confirm O2 flow
- Throttles to idle, turn 90 degrees, maintain a bank angle of 45 degrees and push as
required to descend at the Barberpoll (until 15k(?))
- Advise ATC

The only thing I recall about the rate of descent and view out the front: Spectacular

Most likely this RV has electronic ignition? I'd think you'd have to pressurize the mags to get them to spark efficiently enough to get to that altitude. :scratch:

Elsewhere on VAF he says he has dual PMags and 10:1 compression.

Best comment on that thread (link above from Radomir Zaric): "Just another 1029 ft and you'll never have to worry about terrain again." :lol:

I would be very nervous about the trip back down. RV series have flutter and tail feather issues. Their red line is a real red line and it move backwards with alt, as flutter varries with true airspeed. It's the reason they don't turbocharge them.

Google Bruce Bohannon. He does have a pressure-breathing apparatus though.
