Official: Fighter Jets Caused Sonic Booms along East Coast


TRENTON, N.J. -- Officials say sonic booms heard and felt along the coast from New Jersey to Connecticut were caused by military fighter jets conducting tests.

A Navy spokeswoman says an F-35C and F-18 from Naval Air Station Patuxent River, Maryland, were conducting supersonic testing off the coast Thursday afternoon.

The F-35C has a top speed of nearly 1,200 mph.

Residents reported hearing loud booms and feeling the ground and buildings shake. The booms were heard as far away as Connecticut.

Navy spokeswoman Connie Hempel says supersonic test flights are conducted almost daily in the same area but that most sonic booms aren't felt on land.

She says certain atmospheric conditions can increase the chance of hearing the booms.

U.S. Geological Survey geophysicist Bruce Presgrave says nine booms were recorded over 90 minutes.
