Dr. Abernethy stories about Pratt & Whitney and the J58 engine [video]

The full title of the video is, "Dr. Bob Abernethy Never Told Tales of Blackbirds U2s and Roadrunners the Golden Age of Aerospace". I couldn't fit that so I hope this is a reasonable substitute.

Dr. Abernethy, who passed in 2021, is probably known in the aerospace world more for Weibull analysis (1) than his J58 work, atleast that was the case for me before finding this. Anyone who is an enthusiast of the SR-71 will find it interesting.

(1) A type of analysis used widely to predict failures with limited test or field data.
