What's really interesting about the picture to the left, provided to the AP by a passenger (Pamela Adlon) after the United Airlines Boeing 757 diverted to the Dulles International Airport (IAD) Sunday night en route from JFK to LAX, is that firefighters had entered the plane at all.
Conversations between the aircraft's pilots and air traffic controllers made it very clear that United didn't want to draw any attention to the flight, perhaps a nod to the celebrities said to have been on board???.
A fire in the cockpit at 36,000ft, likely tied to issues with the windshield heater, had been extinguished with halon. The crew had declared an emergency and asked to land.
