It might faster to find if you go directly to the NTSB site at
www.ntsb.gov and when there selecting Aviation, Florida and 337.
It lists several 337 accidents which are both interesting and eye openers. FYI
Question: Would it be an idea for the site administrators to start a new section and collect all the links from the NTSB and others in one place for everyone to be able to easily access and learn from these accidents.
