how did they manage that?

The first one is from when they landed the SR-71 at Dulles to put it in the new Udvar-Hazy Flight museum on the south end of the airport property. It was the planes last flight from California to Washington in 58 minutes. link

Edited to add -
From the link smokecity gave:

"On March 6, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This special airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yielding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, 4 minutes, and 20 seconds, averaging a speed of 3,418 kph (2,124 mph). At the conclusion of the flight, '972 landed at Dulles International Airport and taxied into the custody of the Smithsonian's National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, more than that of any other crewman. "
