NASA has an excellent program for commercial aviation called ASRS (Aviation Safety Reporting System) that also publishes reports of accidents and near misses as a training/learning tool.
They are expanding this to include the UAS community, including hobby, part107, public safety, and part135 users.
Learning from the mistakes of each other is a really critical and effective way to improve your knowledge of the craft and enhancing your overall awareness and hazard recognition to PREVENT these kind of events. Do you really think your the very first to have made a given mistake?
Here is a link to their registration page and web site to either read submitted reports, subscribe to monthly emails, or report an event.
Mishap reporting like this is a part of the Safety Management System (SMS) concept in aviation, and is non-punitive, confidential, and voluntary.
SHARE your experience with others and help contribute to the safety of ALL the system users.
