Missile Mail

We weren't kidding. On June 8, 1959, the US Navy fired a Regulus I missile from the USS Barbero (SSG-317) and directed it to land at the Naval Auxiliary Air Station at Mayport, Florida, near Jacksonville. While the sub was docked at Norfolk, Virginia, Postmaster General Arthur Summerfield helped place two blue and red metal containers, holding 3,000 letters, inside the sub's missile prior to the flight. Check out a video of the experiment, courtesy of British Pathe.

Orangutan Pregnancy

Batang is officially a mom! Meet Redd, her adorable and healthy son.

First-time Orangutan mothers sometimes need help learning how to care for offspring. The National Zoo’s ape keeper exposed Batangn to the experiences of motherhood prior to her baby’s arrival (image left). They gave her a “fake baby” and trained Batang to hold it upright, carry it around the enclosure, present it for bottle-feedings, and give it to keepers when asked through a specially-designed mesh “baby box.”

Phyllis Diller Joke File

This isn’t just any file cabinet—it’s what Phyllis Diller called her “Gag File”. As explored by Megan and Tony, it houses 48 drawers containing more than 50,000 3-by-5-inch index cards, each bearing a typewritten joke or gag that Diller used in her stand-up routine.
