Believe it or not, just last week my son asked me if I had that book. I'd never heard of it. I might have to get it for him for Father's Day--and then borrow it back sometime.He wrote a book about the experience, "Sled Driver".
Just checked both Amazon and Abebooks for a copy. Talk about sticker shock!:shock: Cheapest one I found was $317, and prices in four figures weren't uncommon--sometimes the first figure wasn't even a one! :shock:Believe it or not, just last week my son asked me if I had that book.

I remember a briefing at the USAF museum, the speed of the SR-71 was dependent on the density of the air at very high altitude and the air frame heat.I used to know a retired SR-71 pilot when I lived in Connecticut. He couldn't tell me what the actual top speed of the plane was even though it had been operational for years.
Per either former sled-driver Rich Graham or thermodynamicist Ben Rich, the hard limiter was the Exhaust Gas Temperature, redlined at 860 degrees F. Really cold air let you go a little faster.I remember a briefing at the USAF museum, the speed of the SR-71 was dependent on the density of the air at very high altitude and the air frame heat.
