Socorro so getting their mail was more convenient. The trips into
town also offered them the chance to get their hair cut in a real
barbershop. If they didn't use the shop, Sgt. Greyshock used horse
clippers to trim their hair.



Jumbo


The bomb design to be used at Trinity Site actually involved two
explosions. First there would be a conventional explosion involving
the TNT and then, a fraction of a second later, the nuclear explosion,
if a chain reaction was maintained. The scientists were sure the TNT
would explode, but were initially unsure of the plutonium. If the
chain reaction failed to occur, the TNT would blow the very rare and
dangerous plutonium all over the countryside.

Because of this possibility, Jumbo was designed and built. Originally
it was 25 feet long, 10 feet in diameter and weighed 214 tons.
Scientists were planning to put the bomb in this huge steel jug
because it could contain the TNT explosion if the chain reaction
failed to materialize. This would prevent the plutonium from being
lost. If the explosion occurred as planned, Jumbo would be vaporized.

Jumbo was brought to Pope, N.M., by rail and unloaded. A specially
built trailer with 64 wheels was used to move Jumbo the 25 miles to
Trinity Site.

As confidence in the plutonium bomb design grew it was decided not to
