One man is dead and three others badly injured when a single-engine plane crashed near the Sonoma Skypark Airport. It happened at 12:45 Thursday afternoon, shortly after 38-year old Bill Goldman took off with his 2 kids and either their nanny or their mother (there are conflicting reports). Those children were taken to Oakland’s Children’s Hospital. The woman on board was taken to a local hospital. The FAA and the NTSB are in Sonoma this morning investigating that crash.
