US F-35 fighter jets grounded over pilot oxygen supplies

[mhm]

The US Air Force has grounded a fleet of F-35 fighter jets indefinitely over concerns over pilots' oxygen supplies, according to a spokesman.
F-35 air operations were paused at an Arizona air base after pilots suffered symptoms resembling hypoxia, or oxygen deprivation, Captain Mark Graff said.
Lockheed Martin, which built the jet, said it still plans to show the plane at the Paris Air Show this month.
