The hearing, the second of three days, is focused on the training guidance of the parties involved in the Jan. 29 incident that resulted in the deaths of 67 people. NTSB started the daylong hearing examining the responsibilities and readiness of DCA's air traffic controllers.

Among the 67 people killed in the January midair collision over Washington, D.C., was Chris Collins, an American Airlines passenger returning home from a business trip. His brother, Matt Collins, tells "Morning in America" the loss has been devastating.
