Lily Wu, the mayor of Wichita, Kan., said the airline hasn’t yet released the list of passengers on the flight, known as the manifest. As a result, Wu said she didn’t know how many people from Wichita were on the flight.

Kansas officials are sharing what they know after an American Airlines flight that departed from Wichita crashed in Washington, D.C., Wednesday night.

Officials say more than 60 people were aboard the plane when it and an Army Black Hawk helicopter collided over the Potomac River late Wednesday night.
