PHILADELPHIA (CBS) – A plane that originated in Philadelphia Tuesday morning and landed in Boston was searched after a popping sound was heard from a carry-on bag.

The US Airways flight 1716 left Philadelphia International Airport at 9:24 a.m. and landed at Logan International Airport at 10:16 a.m.
