Notes General:
i) There is doubt as to whether this ship was involved in the mission
ii) The mission was originally scheduled for launch (as Gemini 9) on 17 May but was postponed when the Gemini Agena Target Vehicle failed to achieve orbit due to a booster failure earlier that day. The replacement Augmented Target Docking Adapter (ATDA) was launched successfully into Earth orbit on 1 June, but telemetry indicated that the shroud had failed to jettison properly. Gemini 9 was to launch shortly thereafter but ground equipment failure resulted in a postponement until 3 June. Source:
iii) The letter is interesting in that, as well as the usual pleasantries, it mentions completing several trials of the recovery procedures including the use of a dummy capsule which looks like the real thing. The trials also included fixed wing aircraft, helicopters and UDT swimmers.
iv) All USS Chickaskia covers seen to date have an A added after the 9. As covers from this ship are the only ones seen with a 9 it is assumed that the 9 was added by the ship's Postal Officer to all it's covers. Observation thanks to Eugenio Vespiano.
