On Delta Flight 1641 from San Antonio to Atlanta on March 8th, there were two "special guests" flying in First Class, a couple of penguins (Their names were Pete & Penny) from Sea World. At cruising altitude, the captain allowed their handler to take them for a stroll up and down the aisle so that everyone could take a look at the cute, one-foot-tall penguins and get some great photos and videos.
