The B-36, easily the largest bomber we ever built, was the first long range aircraft able to hit the Soviet Union, bomb them with nukes and return. It featured six R4360 reciprocating engines and four jets, two outboard on each wing. It was configured with pusher, rather than the standard puller props.
The next SAC bomber was a radical departure from typical aircraft layout. It flew with a two man crew and had bicycle landing gear. A dual aft and another dual forward, with outriggers on each wing. When fully loaded with nuclear weapons, it needed Jato bottles to assist in takeoff. These were independent rockets which were mounted near the tail assembly, ergo, Jet Assisted Takeoff. Once in the air the bottles were jettisoned, mostly over water to protect the innocents. Once airborne she could cruise at over 600 mph.
The B-52 which was flying in 1955 was our principle vehicle for MAD, or mutual assured destruction. If Russia bombed us we would obliterate the most of their country and likewise if we bombed them, the same would occur to us. It sped along at a cruising speed of 644 mph. Many are still flying, 60 years later. Thus while I wasn't involved with Korean or Vietnam service, we won the cold war.
We supported SAC in their Reflex Alerts, transporting spare parts, food, ground personnel and pretty much everything needed to operate. Two of our Moroccan bases were essentially empty until SAC arrived, then the skeleton crews that maintained the facilities would open them to the sac troops.
The C-124's that flew in were from Dover AFB, Delaware. On the west coast Travis AFB, California and Mchord AFB in Tacoma, Washington, where I spent the last year and one half of my four year enlistment. We also had C-118s which were the civilian DC-6. It flew about 100 knots slower than my favorite, the C-121, or known as the Lockheed Super Constellation in civilian use.
