(www.defensenews.com)
This is a most excellent place for technology news and articles.
The Russians dropped a 50 megaton bomb from a manned plane without killing the pilots, unless the us is going for the record of largest bomb ever it's not much of a concern beyond ensuring a high enough drop altitude fast enough plane or slowing the bomb with a parachute.
Well the US military could invent the Nova Bomb from Halo. But being in a plane or not wont effect much.
