    A-4 Skyhawk Range, Endurance, Speed, and Time Computer Directly from the Personal Collection of Astronaut Paul Weitz. A 6" circular slide-rule type device with multiple moving disks. This was developed to be used for the first two models of the Douglas Skyhawk attack aircraft, the A4D-1 (A-4A) and the A4D-2 (A-4B). Excellent condition.

    Weitz relates the entire history of this rare piece of aviation memorabilia in a handwritten and signed letter of authenticity on his personal letterhead that accompanies this lot. It states: "The device presented with this letter was called a REST (for Range, Endurance, Speed and Time) computer. It was developed at Patuxent River [home of the Navy Test Pilot School] in the late 1950s. This one is for the A4D-1 and -2. I obtained it when I was an instructor in VA-44, the A4D training squadron in the East Coast Replacement Air Group. It was very useful as a flight planning tool, but apparently never caught on in the fleet. One side depicted cruise and endurance data, while the other side was used for climb and descent. It is from my personal collection of aviation and space artifacts."
