Flight Diverted To Boston After Electrical Smell

U.S. Airways says it is investigating after a flight bound for Europe was diverted to Boston when crew members noticed an unusual electrical smell in the back of the plane.

Flight 710 from Philadelphia to Zurich landed safely at Logan International Airport Thursday night. No emergency was declared.

None of the 192 passengers on board were injured, but four crew members who reported feeling ill were taken to a Boston hospital as a precaution.

The passengers were later put on another plane to Switzerland.
