Levi­athan sailed on 12th June 1929 with 2,132 passengers. As she passed Fire Island, some 60 miles out, a small Fairchild monoplane flew overhead, piloted again by Pond from Keyport airport. This time he found Leviathan quite easily. On his first attempt, Pond dropped a bag of mail into the pick-up frame. The collection wasn’t quite as easy, and he had to make 13 attempts before he was successful in picking up and reeling in the mail bag from the Adams frame. A number of photographers were flying alongside to record the event.
