How it fits. The wind field from the vegetation work (#186) is the input; a kite is a tethered body with lift and drag, a rocket is a projectile with a thrust phase and a parachute. Both can use the existing ball and flight math. The field and the sky are already there.

Scope.

A kite that launches, climbs and dives with the wind.
A model rocket with a thrust phase, apogee and parachute.
A retrieve interaction for the rocket.
A windy-day hint and a calm-day hint.
No damage; a lost rocket respawns.

Related. #186 (wind), #215 (balloon), #214 (drone).

Wind is a physical force; kites and model rockets are how you feel it. A kite on a windy day, a rocket on a still one, and a field to launch from: both are small, physical toys with a clear payoff. They also give the wind field something to act on besides trees. **How it fits.** The wind field from the vegetation work (#186) is the input; a kite is a tethered body with lift and drag, a rocket is a projectile with a thrust phase and a parachute.

Implemented. liuverse-sim::kite is a wing on a line, lifted and dragged by the campus wind with the hand as tether; liuverse-sim::rocket is thrust, coast, apogee, parachute and landing with the wind drifting the chute, and retrieval is the ordinary E interaction. Rockets launch from the AutoMat racks (c4ffdca) and kites from the inventory (b6c6bdd); a rocket left somewhere unreachable returns to the shop instead of stranding the player. Closing as done.
