EAST HARTFORD, Conn. (AP) -

Jet engine maker Pratt & Whitney says heat was the cause of a cracked blade on an engine outfitting the U.S. military's F-35 fighter jet.

Bennett Croswell, president of the company's military engines division, said on a conference call Wednesday that finding the cause was "very good news." He said heat is preferable to the effects of fatigue on the engine part because fatigue spreads, making the problem worse.

What Croswell called "thermal creep" was due to the engine operating longer than usual at a high temperature. He says it was the only affected engine of about 75.

The Pentagon briefly grounded its fleet of F-35 fighter jets on Feb. 22 after discovering the cracked engine blade at Edwards Air Force Base in California.

Pratt & Whitney, based in East Hartford, Conn., is a subsidiary of United Technologies Corp.

    New York is encouraging veterans to go back to school and making it easier for the families of service members who relocate to the state. A new state law signed by Gov. Andrew Cuomo on Monday will give veterans in-state tuition rates at state colleges and universities even if they wouldn't otherwise qualify.

    Images of heavily militarized police in Ferguson, Missouri, make the small Midwestern town look more like a war zone than a suburb. Now some are asking if this type of protection is making the problem worse. Military-style vehicles, and police who are equipped like soldiers in a war are now familiar sights as the disturbances in Ferguson continue and the divide between a mostly white police department and a predominantly African-African community widens.
