Thank you, Rob!

Lockheed's Mach 3 Archangel project aircraft had several names/nomenclatures along its development and test phases. The developed Lockheed A-12 Blackbird was the exact version the pilot was referring to in his quip, from the large page/format book "SECRET JETS, A History Of The Aircraft Developed At Area 51", by Bill Yenne, published by Zenith Press in 2014. (192 pages including many illustrations and an excellent index). I highly recommend the book. Other names from the SR-71 development were YF-12A and for a cover story- a YF-12A was called a YF-12C.

A 1962 version Lockheed A-12 Blackbird specifications follows:

Crew-one.

Powerplant-two 144.57kN (32,500 lb thrust each) Pratt & Whitney J58 afterburning turbojet engines

Design speed-in early 1963, Mach 3.2

Max speed-(cruise) 3661km/h (2,269 mph)

Max altitude-84,978 ft.

Wingspan-55 ft, 7 in.

Length-102 ft, 0 in.

Height-18 ft, 3 in.

Weight-maximum 120,000 lb.

The book is an excellent history of Area 51 including Groom Lake and the Tonopah Test Range near the town of Tonopah, Nevada where incidentally my mother lived in 1912-1914. She was born in 1900; her father took the family west as there was a big silver strike at Tonopah at the time. He was Publisher and Editor of the Tonopah newspaper business that he purchased, but the silver strike petered out and the family returned to Southern Minnesota where he repurchased the local weekly newspaper, the Kiester Courier of Kiester, Minnesota. I appreciated the book's extra information about Tonopah, Nevada, it's test range and Area 51.
