Earth landing coordinates
(Apollo):
163°W, 22°N (Pacific
O.)
Recovery ship:
USS New Orleans (crew onboard in 41
min.)
Mission objectives:
To accomplish spacecraft rendezvous,
docking, and undocking of spacecraft from two countries;
demonstrate a jointly designed (American-Soviet) androgynous
docking system; demonstrate crew transfer and interaction of
crews and control centers.
Results:
All joint activities and unilateral
scientific experiments were accomplished as planned. During
descent and landing, the Apollo crew inhaled nitrogen
tetroxide fumes, which caused coughing and eye irritation.
The crew failed to acuate two earth landing system switches
at the proper time (9000 m); when the manual switches were
hit (7000 m) the cabin was flooded with noxious gas from the
CM s reaction control system thrusters, which were working
vigorously to counteract the swaying motion caused by the
manual deployment of the drogue chutes. CM Pilot Brand was
unconscious for a brief time. The crew recovered once they
began breathing pure oxygen; however, they were hospitalized
in Honolulu for treatment and observation for two
weeks.
