Nat Geo Photo of Mercury astronaut contingency exit training in the Gulf of Mexico. If the spacecraft touched down far from the recovery forces, the plan was to allow the astronaut to exit the spacecraft through the neck area which had previously held the parachutes, rather than the main side hatch. Egress through the side hatch could only be accomplished safely if the divers had already attached the flotation collar or with the spacecraft hatch sill lifted above the waterline by the recovery helicopter. Scott Carpenter, who's Aurora 7 landed far off target, was the only astronaut to use this procedure on an actual flight.
