Heavier objects have more momentum and take longer to decelerate. They're not saying heavy fighters climb better because they are heavier, they are saying heavy fighters can bounce back up and regain a lot of E quickly if they don't blow their momentum. The AHWiki stresses this fact several times when talking about aircraft such as F4U's, F6F's, and P-47's. Search for the word "zoom" in any of the aircrafts' bios: http://bbs.hitechcreations.com/wiki/index.php/P-47D-11

If the rest of their claims are about as unrealistic as that example I think someone needs to do less dismissing and more listening.
Thats simple physics right there, reason behind why a car can stop quicker than an 18 wheeler its all about mass

Yeah, I kind of stepped in it there.  Let me explain.


I understand inertia and drag just fine, the whole F=MA equation, therefore a heavy fighter can carry more force into a climb.   My example was unclear.  What the people arguing didn't understand was gravity.  The argument I was referring to was that a Jug could dive faster because of gravity, that gravity "pulled" it down faster giving it more speed for a zoom climb.  Yes, a Jug can dive faster, but it is because more drag force is required to slow it's inertial force, not because gravity "pulls" it more.


Another one of my pet peeves is how many people misunderstand how jet propulsion works.   I was talking with a moon landing hoax guy the other day, who said it was a hoax, because rockets can't work in space  because there is no atmosphere for them to "push" against.    I tried to explain Newton's third law to him, and that that's how jet propulsion works, but he never got it.

Couldn't or wouldn't, we'll never know.  Some people are so tied up in their own rectitude that they won't admit it when proven wrong, even if they get it.

Some people are just plain stupid too.

At my High School i didn't take physics. I took a class called Physics through aviation. We learned about airplanes, and flew on simulators. Then you could do what i did, and the next year take aviation two at the airport and get your pilots licence.
