Plane Spotting Tips
Best Locations for C-17 Photography
- Joint Base Charleston – Heaviest C-17 traffic; multiple daily departures
- JBLM (McChord) – Regular operations; good perimeter access
- Altus AFB – Training flights mean frequent touch-and-go patterns
- RAF Brize Norton – UK spotters can catch RAF operations
Tracking Resources
- Flightradar24 – Military mode-S when active
- ADS-B Exchange – Often shows military traffic filtered elsewhere
- Planespotters.net – Photo database searchable by serial
