Master Sgt. Tim Huffman says the C-5B plane that was traveling from Germany to Dover Air Force Base in Delaware landed safely at Westover Air Reserve Base in Chicopee just before 2:30 p.m. Saturday.
The base says a young woman was taken to a local hospital with a minor injury.
The plane lost cabin pressure at 34,000 feet shortly after 11:00 a.m. while flying from Ramstein Air Base with 25 passengers and crew.
The incident prompted the military to deploy emergency vehicles at Pease Air National Guard Base in Portsmouth, N.H.; Hanscom Air Force Base in Bedford, Mass.; and Westover Air Reserve Base.
