# Sources

## 3D model
- File supplied by the user: `a-10c-thunderbolt-ii.zip` (copied into `src/`).
- Contents: `source/a-10c_6x_gbu-10_1x_litening_ii_war_thunder.glb` (textures packed in the GLB; loose copies also in `src/textures/`).
- The filename indicates a War Thunder-style A-10C with 6× GBU-10 and 1× Litening II pod. The model arrived via a Google Drive link from the user.
- No licence file was included in the zip or beside it. The source and licence are therefore unknown. This pack is for the user's personal use only; do not redistribute the model or a packaged derivative without a licence from the rights holder.
- The imported GLB is already in metres. Measured size is about 17.58 m span, 16.27 m length, and 3.64 m tall with the gear retracted. Official U.S. Air Force figures for the real aircraft are 17.42 m span, 16.16 m length, and 4.42 m height with the gear down.

## Hover-label facts
Only documented facts are used. Official dimensions and performance figures come from the U.S. Air Force A-10C fact sheet. The earlier draft that called the targeting pod AN/AAQ-33 was wrong: AN/AAQ-33 is the Sniper ATP; Litening is AN/AAQ-28.

- GAU-8/A Avenger 30 mm seven-barrel cannon, 3,900 rounds a minute; twin TF34-GE-100 turbofans at 9,065 lb thrust each; titanium armour around the cockpit that also protects parts of the flight-control system; survival of hits from armour-piercing and high-explosive projectiles up to 23 mm; large bubble canopy with all-around vision; interchangeable left/right engines, main landing gear and vertical stabilizers; published size, speed and ceiling:
