El Toro Dress Rehearsal

Residents in south Orange County will get a sampling of commercial jet noise June 4 and 5 when nine airliners participate in test flights from the Marine Corps Air Station at El Toro. County supervisors, working to convert the base to an internatioinal airport, are expected to give final approval for the $1.3 million test today. Commercial aircraft like those expected to be used at the airport will make 27 landings and 27 departures. All flights are to arrive from the south on runway 34 and depart to the north on runway 34 or to the east on runway 7. Here’s the anticipated schedule:
