The pride and joy of the Luke Air Force Base is grounded until further notice.
55 high-tech, state-of-the-art F-35 fighter jets won't be allowed to fly over the west Valley anytime soon. Military officials at Luke Air Force Base decided to stop flying the jets after five pilots experienced hypoxia symptoms over the past couple of months.
In each case, the plane's back up oxygen system kicked in to help the pilots land safely.
