Back up to Risk & Safety
Propeller injury is the most likely cause for serious injury in paramotor. Maybe even more than other accident types it’s under-reported. I know that from travels where pilots either tell me of one they saw, heard about, or had happen, and it never got reported.
Experienced pilots seem to be at least as susceptible. There are increasingly clever ways to mitigate the risk which is part of what this category is intended to share. The book includes the best of these but more detail is possible here. Accident reports that involve prop injury will also be included in this category.
