What is RotorAlert?

RotorAlert is a free, publicly accessible database of helicopter incidents worldwide. It combines data from the US National Transportation Safety Board (NTSB), international aviation safety records, Wikipedia's curated list of notable incidents, and a daily AI-powered pipeline that scans global news for new crashes.

Every incident in the database includes the date, location, aircraft type, operator, fatality count, severity classification, probable cause, and a link back to the original source - whether that's an NTSB accident report, a news article, or a Wikipedia entry.

How it works

01
Daily news monitoring
Every day at 6am UTC, our pipeline searches global news sources for helicopter crash reports using NewsAPI. Articles are collected from hundreds of international outlets.
02
AI extraction
Each article is processed by Claude (Anthropic's AI) which extracts structured data - date, location, aircraft type, fatalities, severity, and probable cause - from the raw text.
03
Deduplication & storage
New incidents are checked against existing records to avoid duplicates, then stored in our database with full source attribution.
04
Historical data
The database is seeded with over 3,000 incidents from the NTSB accident database (2000-present), the NTSB CAROL report dataset (2016-2023), and Wikipedia's curated list of notable helicopter accidents going back to 1968.
