During a news conference Friday, an NTSB investigator said a technical glitch at Montgomery-Gibbs Executive Airport knocked out a system that gives weather updates to approaching pilots.

A small plane crashed into a neighborhood in Simi Valley on May 3 killing both people and a dog aboard the aircraft and igniting two homes, but no one was reported hurt on the ground despite residents being inside the residences at the time. The community is located nearly 50 miles (80 kilometers) northwest of Los Angeles.
