NIAGARA FALLS, N.Y. — Military C-130 transport planes have been flying out of the Niagara Falls air base for more than 40 years.

That will end Monday when four of the aircraft leave on what will be the final C-130 deployment for the 914th Airlift Wing.

The wing is switching to flying KC-135 refueling tankers as part of a new mission that’s seen as crucial to the future of the air base. The Air Force is retiring some of the C-130 fleet to save money.

The commander of the 914th Airlift Wing, Brian Bowman, will be at the base to see the aircraft off Monday. He says it will be a chance to look back on the past while focusing on the future.
