    A 30 June 1958 resolution authorised development of this astounding weapon, and the draft project was completed on 30 December 1959. Perhaps coming under the heading of 'inadvisable rocket science', test launches would have been into an artificial reservoir in the target area to limit contamination by having the reactor crash into water at the end of its trajectory.
