The crew on this second two day test in the Gulf of Mexico were astronauts Jim Lovell (who flew on Apollos 8 and 13), Stu Roosa (of Apollo 14), and Charlie Duke (of Apollo 16). The test, which ran from April 5 to 7, 1968, followed the same basic structure of the previous one: a 48-hour test of the spacecraft’s post-landing systems with the crew waiting patiently inside. And the crew report was more or less the same: save some communications problems between the crew and nearby recovery forces during the test, it confirmed that the Apollo spacecraft could adequately support a crew of three men during a 48-hour recovery delay. Should the crew splashdown far from their recovery point or in dangerous waters, they would be fine, if uncomfortable, for at least two days; none of the astronaut were keen on the idea of taking the Apollo spacecraft sailing any further. This test’s success made it the final post-landing qualification test before NASA laucnhed its first manned flight – Apollo 7 – seven months later.
