The time at the angle is not relevant. All it needs is one second at a sufficient angle to break the friction of the track. Then the bulldozer's weight will keep it rolling, with any angle on the aircraft whatsoever.

Of course, the pilot can create sufficient angle to break the machine loose. He just could not hold this angle due to decreasing airspeed.

One other point of doubt: Wouldn't the bulldozer be in gear as a matter of principle? If so, it would be effectively impossible to get it to roll and rotate the engine.

Only an idiot would load any vehicle on any form of conveyence and leave it out of gear. And where was the loadmaster? On these two things hang my greatest doubt. My military experience with aircraft (severely limited) was that nothing came aboard without loadmaster approval and also his stowage approval. Same with my flight to Argentina.

I found this interesting (unrelated) story. http://www.radiocom.net/vx6/917.htm

The Bulldozer can still roll if it's in gear, if it was in drive it can roll backwards. I have seen a stalled bulldozer complete it's destiny to the bottom of a ditch.

What kind of angle was required to keep it moving?

The Blue Angels C130 usually performs a JATO takeoff, doesn't it?

Anyway, those are cool airplanes. They flew in a J-model when I was in tech school for KC-135's. That thing damn near pre-flights itself!

AWESOME video, by the way...

Now, I want all this at no charge and at my leisure, so do what you have to do to make this happen ASAP.

I'll settle for an A-10, P-51, B-58, and... F-15.

P-51, oh yeah. That is one of the most beautiful airplanes ever built, IMO.

I also like the looks of the 'Banshee'. Dunno anything about its flight characteristics.

BTW, no joy on the C-130 legend. Doubt grows.

And the sound... wow. Get that V-12 cruising and dive in for a high-speed, low-level pass, and that, friends, is BEYOND COMPARE. My God, that's a gorgeous airplane. "Cadillac of the skies" indeed!

I know for a fact that as long as they are on hard surface, a D-8 will start moving by itself on almost no grade. Just because they're massive and don't have "round" wheels in the typical sense, they still move pretty daggone easily.

FWIW, a couple of years ago, I managed to wangle a 20 minute ride in the bombardier's nose of a B-17G. Sitting there, you're only a couple of feet forward of the disk of the inboard propellers. Talk about noise and vibration! OMG!!! It was like sitting inside a radial engine-powered orbital sander. I was also struck by how exposed you were in that aircraft...no armor, only thin aluminum. Brave souls, those WWII bomber crews were.

Wow, I never would have figured that. I would think all those treads and sprockets must have quite a bit of friction.

But, what does a D-8 weigh? Probably 25K??? or more??

Not hardly; try 36,000lbs...maybe more, depending on how it's equipped.

The Lockheed U-2.

Speaking of intersting carrier aircraft, during Vietnam, there was a planned Deck-landing C-9 (Navy DC-9) COD at one time. It would be used on CVA-41 and CVA-59 aircraft carriers and would have a 30 minute turn around. It even had plans for folding wings and an extended nose gear strut.

Ditch angle

I would say it was a 15 ft drop and 50 ft long.

Based upon what Randy was saying, they appear to roll much easier than I first thought. Maybe one of them did roll out the back of the airplane. Sure hope nothing was underneath it.
