Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

The glider pilot reported that, at 8,800 ft, he encountered a strong sink rate of about 400-600 ft per minute. He added that he was unable to find any thermals and decided to head towards a nearby airport to land. He soon realized that he would not be able to reach the airport and chose to land on a highway instead. During landing, the wings struck road signs and came to rest on the right side of the highway. The glider sustained substantial damage to the wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
