No, the van Allen radiation belts weren't deal breakers for the Apollo astronauts. They really did go to the Moon. Want weekly Vintage Space ? Don't forget to SUBSCRIBE! www.youtube.com/channel/UCw95T_TgbGHhTml4xZ9yIqg
And tell us why there are no jets of flame or exhaust under it. Do you honestly think it connected with the rocket orbiting earth at 4000 mph thru space for the return trip?
Two places where rocket motors can't functtion: under water and in a vacuum. All they had was compressed air and momentum. I don't think they've been to the moon/Levan.

Rockets can certainly work in a vacuum. Jet's cannot as they burn oxygen in the environment, but rockets mix both oxygen and fuel, both stored on board, to produce the thrust. In the vacuum of space, rockets are more efficient as there is no aerodynamic drag on the ship, which factors in favor of the lunar modules lift-off from the moon surface.

To be exact, not "compressed air" but compressed oxygen. Air is only about 20% oxygen, with most of it nitrogen. For space flight, they use pure oxygen, and the Apollo missions used oxygen so compressed it was a liquid, not a gas. And of course, it was more than oxygen but fuel as well.
Apollo went to the Moon with pure oxygen without any further serious incidents, and when the program was canceled NASA finally moved away from pure oxygen in space. The space shuttle and International Space Station programs both took a cue from the Russian Soyuz spacecraft, the workhorse that has been flying since the 1960s that has always used a mixed gas environment. All three environments are very air-like with 21 percent oxygen and 79 percent nitrogen at roughly sea level pressure.
The Saturn V rocket’s first stage carries 203,400 gallons (770,000 liters) of kerosene fuel and 318,000 gallons (1.2 million liters) of liquid oxygen needed for combustion. At liftoff, the stage’s five F-1 rocket engines ignite and produce 7.5 million pounds of thrust.
