Two F-15 fighter jets were dispatched Friday to investigate the movements of an “unresponsive aircraft” over the Atlantic Ocean, the North American Aerospace Defense Command said in a statement. The plane, a Socata TBM-700, did not respond to attempts at communication.

Scheduled to fly from Rochester, New York, to Naples, Florida, the single-engine turboprop plane flew hundreds of miles off course, NBC News reports. The plane’s pilot was reportedly seen “unconscious and slumped over” in the cockpit, U.S. officials said. NORAD believes the plane’s occupants may be suffering from hypoxia; the F-15s spotted condensation on its windows. The aircraft is flying at about 25,000 feet, the Federal Aviation Administration said.

The plane, which holds six passengers, took off from Rochester around 8:30 a.m. ET. It stopped responding to attempts at communication about an hour and a half later, according to the FAA. The number of people aboard the aircraft remains unclear.

The F-15 jets ceased their investigation after the rogue plane entered Cuban airspace. They will resume their pursuit when the plane exits Cuban territory, Fox News reports.
