Retired commercial airline pilot Scott Pattillo and aviation attorney Michael Pearson explain why control systems are at a 'breaking point' on 'The Ingraham Angle.'

Reagan National Airport is widely considered to be one of the more stressful airports in the country when it comes to directing flights, given the intersection of commercial and military aircraft.

Sixty-seven people died in a collision between a Bombardier CRJ700 regional jet operated by PSA Airlines and a military Black Hawk helicopter.

Listen to the air traffic control at Ronald Reagan National Airport speak to the Army helicopter pilots shortly before the deadly crash.

Sen. Tammy Duckworth, an ex-Army Black Hawk pilot, said communications between airline and military pilots usually go through air traffic control.

The ABC7 I-Team has been reporting on air traffic controller staffing issues for years, and Wednesday night's tragic plane crash near Reagan National Airport has highlighted the ongoing issue.

Amid increased concerns about aviation safety, here's how many air traffic controllers there are in the U.S., and how the hiring process works.

The staffing at the air control tower at Reagan National Airport was "not normal" when an American Airlines plane and Army helicopter collided on Wednesday night, a report shows.

Factfinder 12 spoke with a pilot who regularly flies in and out of Reagan National, also called DCA and two aviation attorneys. They all cautioned that it was too early to draw conclusions but provided details on insights and expertise.

Staffing was "not normal" in the air traffic control tower at the time of the deadly mid-air collision near Washington DC between a passenger jet and army helicopter, a preliminary investigation has found.

On Tuesday night, just 24 hours before a deadly collision between a military helicopter and a regional jet at Reagan National Airport, a different passenger jet coming in for a landing at the airport alerted the tower it had to abort. The reason: risk of possible collision with a helicopter.
