The U.S. military grounded all of its new F-35 Joint Strike Fighters following an incident on June 23, when one of the high-tech warplanes caught fire on the runway of a Florida air base.

The no-fly order — which affects at least 50 F-35s at training and test bases in Florida, Arizona, California and Maryland — began on the evening of July 3 and continued through July 11.

All of those F-35s sitting idle could have been a preview of a future in which potentially thousands of the Pentagon's warplanes can't reliably fly.
