November 29, 1961, 3 hours and 22 minutes after launch. The capsule was spotted by a P5M search airplane at an altitude of 5,000 feet. The ships Stormes and Compton were contacted and they moved into position from a distance of 30 miles away. The "Stormes" arrived in the area 1 hour and 15 minutes after landing and hauled the capsule aboard via its lanyard, cracking the onboard window.
Enos, the orbiting chimpanzee fared well. He withstood a peak of 6.8g during booster-engine acceleration and 7.6g with the rush of the sustainer engine.
