DAYTON, Ohio - DAYTON, Ohio (04/2017) -- Four B-25 Mitchell bombers fly over the National Museum of the U.S. Air Force as part of the 75th Anniversary of the Doolittle Tokyo Raid. The aircraft pictured here are Panchito, Betty's Dream, God and Country, and Barbie III.
1M lbs take off weight, topped off fuel tanks, 200 knots, slam on purposely shaved-down brakes ... can this 747 stop? No problem 
Still, 60 years later (retired over 50 years ago), the fastest winged rocket-engine powered, aircraft ever. North American X-15

These are the steps performed to start the engine: 0:08 - The young machine operator begins to pre-lubricate the engine. 0:32 - After reaching 2 bar oil pressure, the older machine operator turns the engine manually. 1:44 - The engine is turned by compressed air with cylinder taps opened to blow out water or oil, if present. The engine is still being pre-lubricated. 1:57 - The machine operator closes the cylinder taps. 2:14 - Water pump switched on (control cabinet in the background). 2:16 - Fuel valve opened. 2:18 - Injection pumps on filling: Probably, this means that the injection pumps are set to maximum as a basic setting (big wheel). The final fuel amount is set by the governer (small wheel in the background). 2:21 - Preheating 2:30 - Glowplugs are glowing. 2:34 - Engine start by compressed air. 2:55 - The machine operator checks the combustion by opening the cylinder taps shortly. 3:13 - Finally, he raises the RPM by adjusting the governor.

I was on the ground for this, they got a FAA waiver to use the runway. There were around 20 planes, parked for inspection, they took off, it was a different loud , the sound of radial engines. They formed up for the missing man formation, for those lost.
The Doolittle Raiders that were able to make it attended, and those that helped the American pilots escape did as well.

It was cool to see one of these flying over an air show almost 25 years ago. So big, and they had it fly by a couple of knots o we stall speed, nose up.

INS Vikramaditya (R-33) STOBAR type carrier and the only one on duty in Indian Navy.
learn something everyday. thanks.
"STOBAR ("Short Take-Off But Arrested Recovery" or "Short Take-Off, Barrier Arrested Recovery") is a system used for the launch and recovery of aircraft from the deck of an aircraft carrier, combining elements of "short take-off and vertical landing" (STOVL) with "catapult-assisted take-off but arrested recovery" (CATOBAR).
Aircraft launch under their own power using a ski-jump to assist take-off (rather than using a catapult). However, the planes are conventional, rather than STOVL aircraft, and thus require arrestor wires to land on the ship. The STOBAR system is simpler to build than CATOBAR. As of 2018 it has been used regularly on Russian, Indian, and Chinese carriers."

One of the modified B-52s - Balls 8, is still being used for development work:
