I'm not trying to do anything unfair here. just trying to make sure I'm not misrepresenting your view of physics. There's a film about 710 recently posted on Youtube made in 1960. Maybe that's the one you've seen.

It's hard to find many good pictures, but here's a quotation from Rod Serling's book (I think I gave it earlier)
"The airliner's fuselage emerged from the black cloud minus its entire right wing and with only a large stub of the left wing still attached. ....
It struck a soybean field at 618 miles an hour. Mud, dirt, grass, shrubs and mottled snow were tossed two hundred and fifty feet in the air. The debris fell back around a muddy crater forty feet wide. From this gaping wound in the earth poured smouldering smoke. There were pieces of wreckage around the perfectly formed rim. Some other metal fragments were hurled 1500 ft away but the one-hundred-foot fuselage itself had disappeared.
In the crater, buried twelve feet under this smoking devil's caldron, was what was left of Northwest Airlines Flight 710 and the 33 men, 21 woman and 8 children and 1 infant aboard.
...
But the residue from Flight 710 was something even the most veteran investigtors had never come across before. There were no bodies.
Newsmen arriving on the scene quickly noticed that the shirts, towels, women's slips, and other items of clothng were hanging from nearby trees. Quite naturally they phoned in the gory news that the clothes had been stripped from the victims' bodies by the explosive impact. Their observation was accurate but their analysis faulty. The items draped on the tree branches were from a bale of old clothing that Northwest was shipping to its maintenance shop in Miami for grease rags. When impact burst open the baggage compartment, the assorted clothing was flung into the air and fluttered down among the trees.
Where were the victims? Masked workers wearing plastic gloves dug into the smoking crater. They dug down a full twelve feet before they found what they were seeking. The huge fuselage had telescoped and compressed into a mass of molten metal only one third its original length. Of the sixty-three occupants, there was not enough left to identify - eventually - more than seven bodies. The aluminum fuselage that was their coffin was so hot that five days later a steam shovel picked up pieces that still were burning."
