AtD, that ending again: SPOILER

[Mark Kohut]

In One Minue to Midnight, p. 195, there is good stuff on all of the Cold War nuke bomb testing RESUMED in 1961 and 1962.

Here is one account of a Soviet practice:

 "Gruz poshyel," reported the pilot of the Bear, as he passed over the drop zone and banked steeply away ("The cargo has gone.")
 The 260-kiloton bomb floated gracefully down to earth on a billowing
parachute. The crew of the two bombers donned their tinted goggles and
waited for the flash."
