On a trip to las vegas in 2004, observing from my east-facing hotel room in the pyramidal Luxor Hotel at daybreak, I watched a fleet of six unmarked 737s make commuter flights to nowhere. These aircraft depart every weekday morning from a tidy, anonymous terminal on the western side of McCarran International Airport. A long line of cars pours into a 1,600-spot parking lot as the jets pull away from the terminal, taxi to the runways, and head out into the desert sky. At the end of the day, the shuttle flights return and the lot empties. The passengers go home and tell their families nothing about what happened at work that day.

...Those unmarked 737s were ferrying employees to the flight-test center near Groom Lake, Nevada, known to the public as Area 51. The gray airplane is Polecat, a next-generation stealth unmanned aerial vehicle (UAV)--Cappuccio's video was his sly way of unveiling the program. Those earthquakes? Quite possibly sonic booms from a long-suspected hypersonic attack vehicle, a sleek aircraft that has consumed the imaginations of black-project enthusiasts and military analysts, including me, for two decades. Though seemingly dormant in recent years, the program appears to be on the move again, and with a renewed vigor that has me feeling, soewhat unsettliingly, a bit like the aerospace industry's own Ahab.
