Thanks for posting, Bill. I have long wished I could find a copy of the story about the mid-air collision of the XB-70 bomber in June 1966. It touched me deeply, as I had spent five years as a lead engineer in the design of the portion of the airplane that included the cockpit and ejection system, before moving from L.A. to Seattle. I was stunned when I first saw the headline on the day following the crash, while I was at my first (of several) AA workshops in Yosemite. It was an incredible story that Life published later of the detailed sequence of events of the collision, including the struggles of the pilot to successfully eject and the co-pilot who was not so fortunate. The system was designed to allow ejecting at 70,000 ft altitude at Mach 3!, maintaining the "shirt-sleeve" environment of the cockpit sealed into the capsule (while the outside surface of the plane was at 450F/232C).
For anyone interested, p.126:
BTW, it's helpful to use the two-pg spread display mode and the magnifier to read through the article, while ignoring ads.
