From the README

A browser-based MiG-21 reconnaissance flight experience over procedurally generated Himalayan terrain.

Fly a recon sortie through the high Himalayas at 250 m/s. Find five fictional observation posts hidden on ridgelines and passes, frame each one through a nose-mounted optic, bring back usable photographs, and come home.

No weapons. No dogfights. Terrain is the only thing out here that can end the sortie.

Keyboard, gamepad and touch are all first-class; the briefing shows whichever one you last used.
