The last few days has brought a lot of serious news about Navy SEALs, as the military continues to investigate whether classified information was released about the 2011 raid that killed al-Qaeda leader Osama bin Laden. SEALs were also warned Friday about the perils of book publishing and publicity, and told not to be “selfish” by sharing military secrets.

Yesterday brought a moment of levity, however. Just before the Dallas Cowboys and Arizona Cardinals squared off at AT&T Stadium in Arlington, Texas, a Navy SEAL and his dog descended from the heavens onto the football field, rappelling from the monstrous scoreboard hanging over the field.

The scene has become an Internet sensation. Tweets from the NFL on it have been shared widely, with some speculating the dog loved the adventure and some sure that he hated it. On Facebook, it has gotten more than 66,000 “likes” and 8,600 shares in 24 hours.

Using military working dogs in fur-raising circumstances is nothing new, of course. They have worked alongside U.S. and coalition troops in combat zones for years, sniffing for explosives and even sometimes jumping from airplanes while attached to their handlers. In fact, they’ve used parachutes since at least World War II.
