There have only been a few high altitude nuclear explosions. There have been none since November, 1962. At that time, scientists were just beginning to understand the phenomenon well enough to even know what to try to measure. This means that there is a very limited amount of data available, and only a part of that data is unclassified.

Sorry, won't go into detail with what I know here. Just giving a teaser.
The last truly black aircraft that came out was the F-117. Just before we left Pease AFB in 1983, they took something like 100 pilots and maintenance personnel from the 509th Bomb Wing to work on making the A-7 Corsair supersonic and night capable. *coughcough* We found out years later they went to Tonopah and were with the Nighthawk program.edit on 1/16/2013 by Zaphod58 because: (no reason given)
Lockheed Martin says it is not disputing the facts laid out in the Pentagon's Director of Operational Test Evaluation (DOT&E) report on the company's F-35 Joint Strike Fighter (JSF), but says that many of the issues raised have already been addressed.
"The challenges that are identified in the report are known items, normal discoveries," says Steve O'Bryan, Lockheed's F-35 business development director. "When you look at it from a holistic sense, when you really talk about beginning OT [operational test] in 2017, these are known discoveries, known challenges, and the kind of normal discoveries you'd see in a flight test programme of this size and complexity." Despite the problems highlighted in the report, O'Bryan says 2012 went very well for the stealthy tri-service fighter. "In my humble opinion, it was our best year on the programme," he says.
There have been a number of significant achievements over the course of the year-more than 65% of the F-35's total of 5000 flight hours have been accumulated in 2012, O'Bryan says. "If you look at flight test overall, we remain about 5% ahead of plan," he says. The F-35 has had its first weapons release and the A-model has flown to its maximum speed, altitude and angle-of-attack. Also, both the A and B model jets have completed engine air-start tests. O'Bryan adds that at this point, the F-35 is more than one-third of its way through its flight test programme. "We are on track to finish development in 2016," he insists.
