The atmosphere is not as volatile as the natural gas in a residence that, once left leaking with the windows closed will ignite with one flip of a light switch.
A very good point. By the time of the first test, they knew that this would not happen; see, for example, the Wikipedia article on the Manhatten project (I've also read this in other sources, but Wikipedia is quick to link to):
Quote:
Teller also raised the speculative possibility that an atomic bomb might "ignite" the atmosphere, because of a hypothetical fusion reaction of nitrogen nuclei. Bethe calculated, according to Serber, that it could not happen. In his book The Road from Los Alamos, Bethe says a refutation was written by Konopinski, C. Marvin, and Teller as report LA-602, showing that ignition of the atmosphere was impossible, not just unlikely.[7] In Serber's account, Oppenheimer mentioned it to Arthur Compton, who "didn't have enough sense to shut up about it. It somehow got into a document that went to Washington" which led to the question being "never laid to rest".[8]
So, this is actually a good analog to the present situation with the LHC - the scientists involved in the project are well familiar with the physics and the risks (or lack there of) involved in it.
