Did glare from outdoor lighting in Washington, D.C., contribute to last month's air disaster there?
"Our examination shows how the American Airlines jet and the second plane, though separated by miles, would have appeared close to one another near the horizon and the helicopter crew could have confused the two jets when the tower first warned of incoming air traffic. The examination further shows how around a minute later, as viewed from the helicopter cockpit, the lights of the incoming American Airlines jet could have been obscured by the glow of the city skyline, allowing the jet to go undetected."
