Something fishy bout this one.

Where did you get this? No sane US Air Force pilot would dare try that stunt. It would surely cost a pilot in our military his carrer to pull that stunt. Bombers aren't built to fly inverted.
Air sampling missions were routinely conducted over the Far East, Indian Ocean, Bay of Bengal, Mediterranean Sea, the Polar regions, and off the coasts of South America and Africa. The WC-135W played a major role in tracking radioactive debris from the Soviet Union’s Chernobyl nuclear plant disaster. Currently the air-sampling mission supports the Limited Nuclear Test Ban Treaty of 1963, which prohibits any nation from above ground nuclear weapons testing. The WC-135W is currently the only aircraft in the inventory conducting air-sampling operations.

This is what a Spitfire looks like after exceeding mach 0.9 - yes, it landed like this.
There is indeed a story to that pic, here's what I wrote about it some time ago on another thread;
some opinions I put here may have since changed
In RAE trials during 1943-46 various fighters were dived at full power from 40,000ft in what the test pilots desctibed as 'an attempt to break the world air speed record vertically downwards'
As part of these trials, once the terminal velocity was reached the guns were fired, and I quote, 'to see if the wings came off'. Nice work if you can get it!
It is recorded that in these trials the highest mach number ever recorded on a piston engined aircraft in flight was obtained when Sqn Leader A Martindale, in 1946, dived Spitfire XI 'EN409' to a speed of mach 0.92. However the photo below shows both what that speed did to the Spitfire and what a skillful pilot Sqn Ldr Martindale was! The propeller was ripped clean off and the fron end looks like its been repeatedly bashed with a lump hammer. And yet it appears to have landed perfectly.
The account goes on to note that several other types were tested in this way, including the P-47 Thunderbolt and P-51 Mustang and none of them were able to reach the speed of the Spitfire because their high speed drag increased more rapidly. The major reason was in RJ Mitchells choice of a thin wing tapering to 9% thickness chord ratio, this was thinner than all other wings (even the P-51!) and against all aerodynamic advice of the time.
They alsdo found that NACA work oN laminar flow (NACA pioneered this work, not the RAE) was basically sound but that the promised advantages were not being obtained in practice. This was traced to surface roughness of the wing finish leading to skin friction which was cancelling out the benefits of laminar flow. This led to a change in the way the P-51 wing was manufactured and to the design of a laminar flow wing for the Spitfire, which led to the Spiteful.
