The Pentagon has proposed restricting civilian air traffic above much of the Johnson Valley Off-Highway Vehicle Area to expand and support training exercises. But those who frequent the area just west of the Twentynine Palms Marine base say the proposal would severely limit recreational access and reduce safety. They say the airspace restrictions could prevent rescue helicopters from evacuating injured motorists, and threaten the famed King of the Hammers off-road race that's held there each year.
Brendan Sobie, a Singapore-based aviation analyst, emphasizes that it's not unusual for airlines to reroute due to conflicts, but the current situation is particularly complex due to multiple airspace restrictions occurring simultaneously.
