Congressman Richard Hanna is calling on the U.S. Department of Transportation to ensure the contract control tower at Griffiss International Airport remains open.

Hanna and 82 members of Congress have sent a letter to Transportation Secretary Ray LaHood.

It urges the Department and the FAA to use funds made available through the "Reducing Flight Delays Act of 2013" to prevent the closure of 149 air traffic control towers nationwide.

The FAA plans to close the contract tower at Griffiss on June 15th.
