Two drawings, side and aft, of the Mercury spacecraft show the proposed location a posigrade rocket package to separate the vehicle from the either a Redstone or Atlas rocket during an emergency. The normal escape tower forward of the spacecraft has been replaced with an aerodynamic spike, providing overall weight reduction. The proposed posigrade rockets would be either Thiokol Patriots or Rocketdyne P-4's. This configuration called for astronaut escape from the pad and up to 20,000 feet altitude via an ejection seat.
