Most Lockheed Martin (LMT) F-35 fighter jets have been inspected, after the entire fleet was grounded last week. The U.S. military had suspended all flights after an engine broke apart and caught fire at an Air Force Base in Florida.
The incident has put contract negotiations for the next batch of fighter jets and engines on hold. The warplane's engine is manufactured by Pratt & Whitney (UTX).
The F-35 was also supposed to make its international debut at two air shows in Britain on Friday and next week, although no decision has yet been made on whether to allow the jets to fly to Britain.
