Responders are working to recover the victims of Wednesday night's midair collision over Washington, D.C. It could be the deadliest crash to occur in U.S. airspace in at least 15 years.
"More and more planes on this busiest runway in the United States is just going to increase the chance of a significant incident," Sen. Tim Kaine warned a year ago.
Tragic midair collision between American Airlines jet and U.S. Army Black Hawk near Reagan National Airport leaves no survivors. Recovery efforts ongoing.
