The alternative music community is in mourning after a private jet hit a power line in foggy weather early Thursday and crashed into a San Diego neighborhood, killing multiple people on board. Among them was the groundbreaking music executive Dave Shapiro,

Dense fog had rolled into the area around the time the plane was approaching the airport. Visibility was at half a mile at 3:55 a.m. and had dropped to a quarter of a mile just after 4 a.m. in the area around Marine Corps Air Station Miramar, which is just a few miles north of the crash site, according to the National Weather Service.
