The SR-71 was a fascinating spy plane, but the grandfather of them all is the U-2. The U-2 actually outlasted the SR-71, which was originally intended to be its replacement. The linked article discusses the chase cars which followed the U-2 to assist it in landing.
A summary of how to land a U-2 spy plane:
Slow down, fly down to the deck at around 140 mph.
Have chase cars drive on runway, hauling ass behind you and offering radio advice.
Land plane in polite, controlled crash.
Don’t screw up.
