Pentagon says to resume F-35 flights

WASHINGTON (Reuters) - The Pentagon said on Thursday it would resume flights of its F-35 fighter jets following a week-long precautionary grounding imposed after a crack was found on an engine blade on a test plane in California.

"F-35 flight operations have been cleared to resume," Pentagon spokeswoman Kyra Hawn said in a statement. She said flights could begin as early as Friday, depending on weather conditions.
