In brief: Varies. Some local anesthetics wear off within 30 minutes, while other are specifically designed to be active for up to 20 hours. It depends on the type and location of the drug. Talk to your anesthesiologist or dentist about medications that they will use. Would you like to video or text chat with me?
Ronnie Van Zant was killed by blunt head trauma. He had about a quarter sized bruise on his right temple. This occurred in the October 20, 1977 plane crash.
Ronnie Van Zant, Steve Gaines, Cassie Gaines, assistant road manager Dean Kilpatrick, pilot Walter McCreary, and co-pilot William Gray were killed on impact; the other band members (Collins, Rossington, Wilkeson, Powell, Pyle, and Hawkins), tour manager Ron Eckerman, and road crew suffered serious injuries. Ronnie Van Zant's widow, Judy Van Zant Jenness, operates a Lynyrd Skynyrd tribute website for the educational purpose of sharing the original Lynyrd Skynyrd band's history, as well as Freebird Live, a live music venue in Jacksonville Beach, Florida.
