The US Lockheed U-2 Spy plane is arguably one of the most capable platforms in the sky, but it needs backup when it comes in for a landing.
With only two wheels, the aircraft is incredibly unsteady when it touches down, and pilots have their hands full during the entire landing process.
The solution? Send a back-up pilot to trail the plane in a car while offering control inputs. The ground pilot can reach speeds around 140 mph while attempting to keep up with the aircraft. And without his help the plane could ground loop or worse.
Yes, it is as insane as it sounds.
