Concerns that a deadly collision could occur at Reagan National Airport had long been building. But attempts to draw attention to potentially dangerous conditions sometimes went unheeded.

The Army helicopter that collided with a passenger plane above the Potomac River boasted an experienced crew doing “an unforgiving job.” Friends and relatives are still baffled and mourning their loss.

No one was injured, but a passenger on one of the planes described “violent shaking” and a “really loud crunching sound.”

Remains of 55 of the 67 victims have been recovered, officials said on Sunday as they prepared to lift the wreckage of the jet out of the Potomac River on Monday.

Transportation safety investigators are seeking to determine if the pilots of the American Airlines plane detected danger just before the midair crash with a helicopter.
