takeoff

AP - The Federal Aviation Administration is studying whether to again change takeoff and landing procedures at John F.

Kennedy International Airport after a second near-collision of aircraft in less than a week.

A visit to Adacel, which develops software primarily aimed at the air traffic control industry.

The collision happened Thursday afternoon as the red aircraft was waiting to takeoff and one was coming in for a landing.

A Congolese jetliner carrying 79 passengers and crew crashed on takeoff Tuesday, careening off a runway into a busy neighborhood and bursting into flames.

At least 21 people were killed, but most of those aboard survived, an airline official said.
