BANGOR  — The commander of the Air Mobility Command at Scott Air Force Base, Ill., is visiting the Maine National Guard’s 101st Air Refueling Wing as part of an assessment that will determine the future of the so-called air bridge program.

The program that provides in-air refueling of military aircraft headed to and from Iraq, Afghanistan and Europe has been targeted for cuts. About 400 personnel in Maine, New Hampshire, Pennsylvania and New Jersey are only assured of continued service through the end of November.

Gen. Raymond Johns is scheduled Thursday to tour the 101st in Bangor along with Maine Sen. Susan Collins and Gov. John Baldacci.

Collins has said she hopes the general’s visit will lead to the vast majority of personnel being retained through the coming year.
