BOSTON (AP) – A US Airways flight from Manchester, N.H., was diverted to Boston Thursday afternoon after several passengers reported a sulfur like odor in the plane.

Flight 1025 was headed from Manchester to Charlotte, N.C., when some passengers started talking about the smell and feeling lightheaded.

Massport officials said the plane’s 116 passengers and five crew members were evacuated after it landed at Logan Airport at about 1 p.m. Four passengers reported feeling ill, and were being evaluated by medical personnel.

Massport spokeswoman Danny Levy said the source of the odor had not been determined.
