Good god. Glad to hear they all made it; the pilot looks like he has a serious head injury.

Didn't check the charts and got too far overloaded for the altitude?

I'm no pilot, but it seems to me that after the 2nd touch-and-go that I'd be able to tell I was going nowhere fast and put it down safely, unpack two dudes, then fly two trips.

Or better yet, wait for evening/the next morning to fly out. Supposedly, the aerodrome elevation there is 6400' ASL, and with the temperature that day, the density altitude would have been between 8500' and 9500'. He'd have been hard-pressed to get out safely by himself, much less with two passengers aboard. Also, I doubt the explanation of "hitting an air pocket"...forests create areas of sinking air above them, on account of the cooling effect they have.

I sure wish I had that much amazing flat area to do a forced landing in if I bothered to take off overloaded for the conditions. I have a wall of trees though. Lucky idiot.

It looked to me like the pilot tried to turn just before the crash. My guess is that he had barely enough lift to stay airborne in straight-and-level flight, but not enough to keep altitude through the turn. The "air pocket" was a BS explanation for the buffeting at the beginning of a stall.

3 full size dudes (and their gear) is really pushing it for that plane near sea level. On a warm day at that altitude? Asking for it. I see this regularly at our little local airpark in northern California. "It's a 100 degree day, lets all pile into the Piper and head to the coast! OH gently caress!" What a video though! Pretty amazing how it goes through the trees like a weedwacker, I thought they would be less forgiving. The ground, however...

Classic hot & high. Their start airport was probably lower in altitude and earlier in the morning. It's a shame to see vintage aircraft destroyed by vintage mistakes. https://www.youtube.com/watch?v=RZCb6nw_T4U Glad they all lived and that the pilot will recover. Also, I thought trees had a heating effect and that gliders etc use wooded areas for thermals. Doesn't matter that much, the mistake is taking off too heavy for the conditions. The local air currents just determines the location of the accident.

grover posted:It's simply the reverse of a thermal; fly over buildings and air goes up. Fly over a nearby forest and air goes down. It's most readily apparent when you're flying an R/C airplane, especially gliders or elevator-less 2-channels. I get the concept but the temperature differential would have to be pretty extreme for that I'd think. Using buildings to climb a skydiving parachute is fun!

When I was there, there was definitely a 747 there (iirc it's a school) and I think it was green/white. That was the TDY where I left my cell phone in the rental van and was going TDY 2 days later so I had to buy a new one.

The temperature differential is very small actually. Thermal activity occurs when there are unstable conditions in the air. Any tiny disturbance causes a bubble of rising or sinking air. I wonder of most of that guys facial trauma was caused by the Ipad on his yoke?

It doesn't take much to get a pretty noticeable circulation over a forest; remember that the trees are constantly transpiring water during the day, cooling the ambient air above them, which in turn sinks (and in a mountain valley, flows downhill to the valley bottom, creating a circular flow). I don't know whether the pilot's head hit the iPad or the glareshield, but I do know he probably would have escaped most of his injuries if his aircraft was equipped with a shoulder strap.

I just learned that Endeavour is going to be flying into LAX on one of the days I'll be at Disneyland. What are the odds they'll do a fllyover of Disneyland, or am I going to need to rent a car and get myself to LAX for a side trip?

Probably pretty slim. I'd expect it to pass a few miles to the north, inbound to LAX unless they spend a bunch of time in the pattern. I have no idea what the pattern looks like for LAX, but I doubt it flies that far SE.

They might make a pass, though. They did a bunch of photo-op flyovers of NYC before they landed Enterprise here.

Skilled glider pilots can stay aloft damned near indefinitely, solely by soaring through thermals.

That may be true, but really all the sink did was cause the crash into the trees a little sooner than planned. That aircraft was not going any higher, barely out of ground effect and arguably on the backside of the power curve just to stay where it was. At least the pilot didn't try to pull a 180, probably would have resulted in a nice quick stall/spin nose first into the ground.

He was almost stalling the wing just before it crossed the first set of trees if you watch the secondary camera, anyway, so yeah, the downdraft just sped up the incident.

Anyone know if this model of Stinson would have had a stall warning system? Couldn't hear any horn in the video, and like I said he was definitely on the backside of the powercurve, probably right into slow flight range a couple of times before the sink started occurring.

i'm wondering if keeping hte plane in ground effect longer, letting it get "faster" would have let him get flying versus hanging on the prop like that. Definitely a behind the power curve thing there. But ... it also could have been a spot where behind the power curve was the only place it would fly.

Their headquarters is in Montebello, CA, so I'm guessing it's there or at one of the many hangars in the LA area. Looks like we'll be seeing it fly before the end of the year. Another video of the LEMV: https://www.youtube.com/watch?v=pOIEO6h1fy0

  That just about beats any Blue Angels performance I've ever seen, goddamn. I guess the engine upgrades for the B-52 were so it had enough power to carry the pilots' massive brass balls.

A bunch of random stuff I've been meaning to post: It looks like we missed out on an atomic powered drone. http://blogs.ottawacitizen.com/2012/03/25/no-go-on-a-nuclear-powered-unmanned-aerial-vehicle/ Also, remember when that drone was lost in Iran, and we argued about if the GPS had been hacked, and the general consensus was that it was impossible? Welp: http://rt.com/usa/news/texas-1000-us-government-906/ A new Wave Rider thing is going to be tested: http://www.bbc.com/news/technology-19257769 Thanks to model nerdatry I came across some interesting stuff about the Hs 129. The giant cannon that we all remember was not the only experimental weapon that the facist gnomes were developing for it. Other attempts include: 210 and 280mm rocket tubes, 70 and 55mm unguided rockets, and the Gero flame thrower. (!) They also tried fitting a downward-firing mortar: 6 downward facing barrels in a rhomboid shape.  Speaking of Nazi science, apparently this odd looking thing was going to shoot down B-29s when they appeared over Germany. It used the wings, tail, and engines of an Me 262, and had an armored fuselage with many cannons sticking out in all directions. Hawker Sea Fury(?):   Images from Life:   The story behind this picture: a fighter squadron started decorating their helmets, and got the idea to see what a local university art department could do with them.  I totally forget the story behind this.   An-124s: still p. big
