Source: Originally from https://github.com/FGMEMBERS/737NG
Models: b737

All models have been optimized for web delivery:

- All textures stripped (materials set to neutral unlit white)
- Meshes deduplicated and pruned; most models simplified
- No Draco compression (avoids external WASM decoder dependency)
- B737 model converted from glTF 1.0 to glTF 2.0
