Three.js r170 is embedded in the executable HTML and licensed under MIT.
To rebuild the source project, restore three.embedded.js from the first IIFE in the decompressed HTML, or bundle three@0.170.0 exposing window.THREE.
The duplicate library bundle is omitted from this source archive to keep the single-file download compact. The original F-22 model, conversion code and GPL-2.0 license remain included.
