Bell Pogo
Bell built several versions of the rocket POGO under contract with the NASA because it was intended to be used as a means of transportation on the moon during the Apollo missions; however NASA decided not to use the POGO because of the risk of a crash, and decided to send the Rover car instead of the POGO. Bell demonstrated that all the versions of the POGO flew in Earth atmosphere.
The first POGO was a single place model with a vertical tube with a stand for the pilot to stand with the rocket engine and peroxide tanks at the front.
A second POGO was the two place POGO that was able to carry a passenger in front and it was controlled from the back, this POGO had the rockets and tanks between the two pilots.
A last version of the Bell POGO was the "reverse" POGO built with the rocket engine and the peroxide tanks at the back and Bill Suitor was the only Bell pilot to fly the reverse POGO.
