The following recounts an incident in 2004 that advocates of research into U.F.O.s have said is the kind of event worthy of more investigation, and that was studied by a Pentagon program that investigated U.F.O.s. Experts caution that earthly explanations often exist for such incidents, and that not knowing the explanation does not mean that the event has interstellar origins.
WASHINGTON — Cmdr. David Fravor and Lt. Cmdr. Jim Slaight were on a routine training mission 100 miles out into the Pacific when the radio in each of their F/A-18F Super Hornets crackled: An operations officer aboard the U.S.S. Princeton, a Navy cruiser, wanted to know if they were carrying weapons. […]
“Well, we’ve got a real-world vector for you,” the radio operator said, according to Commander Fravor. For two weeks, the operator said, the Princeton had been tracking mysterious aircraft. The objects appeared suddenly at 80,000 feet, and then hurtled toward the sea, eventually stopping at 20,000 feet and hovering. Then they either dropped out of radar range or shot straight back up.

Hovering 50 feet above the churn was an aircraft of some kind — whitish — that was around 40 feet long and oval in shape. The craft was jumping around erratically, staying over the wave disturbance but not moving in any specific direction, Commander Fravor said. The disturbance looked like frothy waves and foam, as if the water were boiling.
