Cessna 421 Unresponsive Over Gulf of Mexico

[in reference to Payne Stewart's crash] "The plane flew more than halfway across the United States, apparently on autopilot, until it crashed in a South Dakota field." (last part of the article from above: http://news.blogs.cnn.com/2012/04/19/pilot-unresponsive-as-small-plane-circles-above-gulf/)

Just a brainstorm...envisioning a future where if the autopilot is engaged, intercept aircraft can "remote in" and take control over the aircraft through the autopilot and fly (like a drone) it to safety, or at least away from further harm like a populated area. I'm sure this would be relatively attainable with existing technologies.

It would be expensive to mandate GA to be equipped with this. Less likely to happen in a two crew environment

May work great until a hacker takes over the system.
 
The up/down trend of the speed is it stalling and nosing over.

My former CP used to be in flight test for the Hawker program at HBC. They did a little experiment one day; an emergency descent with air brakes extended. They let the autopilot level off at 10,000 feet after a Mmo/Vmo dive. They left the air brakes extended and kept hands off to simulate two incapacitated pilots. When the plane leveled, it obviously slowed. When the stick shaker activated, the autopilot disengaged as designed, and the aircraft started into a parabolic pattern for the next 6 minutes (I think that's what he said; regardless, it did it for a LONG time) until they had to take over so as to not put themselves into an unrecoverable situation.
Or it's just his groundspeed fluctuating has he makes the circle. If you look on the track west headings are always slow and east headings are always fast.
 
Probably a stupid question - but if you are flying single-pilot in a pressurized airplane are there any precautions that can be taken against hypoxia, or protocols to be followed. How much more dangerous is single-pilot than dual in a pressurization problem scenario - would both pilots zap out at the same rate?

Forgive the ignorance - real airplanes have huge roll down from windows like my avatar - so I'm inexperienced in such matters.
 
Sad news.

I overheard the military trying to raise this aircraft on guard recency while I was doing an IAH-ABQ turn. So that's what it was!

Have one of these http://www.sportys.com/PilotShop/product/13010

I would also recommend people go to a chamber to actually experience it first hand.
 
This doesn't look like the Payne Stewart type of pilot incapacitation - unless the AP wasn't on. At 8:30, things go wrong, and it looks like the airplane may have been in reasonable trim, but no one (or thing) was flying it. If the AP was on, it would have just stayed straight and level, run out of fuel, and then gone through the stall/recovery cycle until it ran out of altitude.

The paper this morning said the plane is in 1500 feet of water. We'll probably never know...

I want to agree. Did you guys see the track log? The plane got up as high as 33,000'!! I can't imagine the autopilot being on, I just wonder if the AP disconnected but it was still trimmed out well enough to keep flying along like that? The thing that throws me off completely, is the initial turn off course is to the southwest. I don't quite understand how it made such a long turn to the southwest and then began turning to the northeast before starting all those turns.

I feel bad saying it, but does anyone think it was suicide? How would the AP disconnect (which I'm assuming it did, otherwise it wouldn't be climbing and turning like it was)other than forced control input or a possible stall? The ground speed doesn't seem to ever get low enough though to stall.

Seems like a good plan if the guy was thinking suicide. Go up to high altitude on a trip that takes you over the gulf. Dump the cabin in the middle of the trip and just pass out. You're over the ocean so you'll never hit anything/anyone. Hopefully that's not what it was, either way, sucks to hear

You're overthinking this a lot, and there is a large difference between the AP in a jet and an AP in a Twin Cessna

The AP was probably on in a cruise climb trim and power setting.

At some point the cabin pressure failed and/or the pilot lost consienceness.

The airplane kept climbing untill it entered a power on stall (which will be at a much higher airspeed at 33K than at sea level).

The stall caused the AP to disconect, and the airplane pitched nose down and slightly wing low

After pitching down, the plane recovered to a cruise climb and stalled again in a phugoid (sp?) osscilation. This kept going on for some time.

At some point the different fuel burn from the engines shifted the lateral CG and caused the plane to roll the other way.

Eventually it ran out of gas and crashed.
