Pat, When Einstein wrote the letter to Roosevelt about the possibility of developing an atomic weapon, it was to warn him that he believed that Germany was developing it. He didn't know that Werner Heisenberg had advised against it thinking, as Hitler did, that the war would be over too quickly. It was only the problems with getting a perfect implosion for the plutonium bomb and the slow production of U-235 for the gun barrel bomb that kept Berlin from being the monument that Hiroshima is today.

Hi,
I assume that the use of the bomb against Japan was done as quickly as possible after getting it to work at Alamagordo. It wouln not have been possible to deploy it against Europe as the war had already ended. I don`t think that a tactical atomic SHELL for battlefield use became possible for some years. Tanks were not equipped with them until well into the Cold War when hordes of Russian tanks were expected to storm across Europe. It would be interesting to know when planning for an atomic shell was started. There was only a limited supply of U 235 available. Not enough I suspect to have too many lines of experimentation goin on.
Had you seen that interview with Tibbetts before?

No, but I have read about America's nuclear research and arsenal for years. U-235 was the quick way to a bomb, but it literally had to be built in the air on the way to Japan, since it will fission and explode if too great a quantity is brought together. When Tibbets was talking about the two scientists that rode to Hiroshima with him, that's why. The U-235 bomb was never tested until they used it. They hadn't produced enough to make a practice bomb. Plutonium, on the other hand can be stored safely without worry since it has to be compressed by conventional explosives to get it to explode. If you bring too much of it together it will just generate a lot of heat and melt.

PS, Yeah, John, we'll stop.

Okay, Aviation related, if not directly Kolb. You might have read the review of Aerocinema.com in last month's issue of "Sport Aviation". I figured at $9.95 for a three month trial, well, I spend that much on bottled water in three months. Anyway, lots of great 30 to 35 minute documentaries about aircraft. One of the coming features is on America's nuclear powered bomber project of the 50's. They actually flew a reactor in a modified B-36 and ran it inflight. Of course there's been a lot of work on miniaturizing reactors since then so it might be doable. Getting the license to fly it might be a bit of a bother, though.
