Luke F-35s still grounded

The F-35A fighters that were grounded at Luke Air Force Base, Ariz., last week will remain on stand-down indefinitely. The Air Force is continuing to look into what caused five pilots to experience hypoxia in incidents going back to May 2. The planes were grounded June 9. The base has 55 of the 220 F-35s that are flying worldwide. The Navy also had oxygen issues with T-45 training jets, and back in 2011 there were similar issues with F-22 fighters.
