Educational visualization — not real-world safety guidance.
The illustration is an atmospheric interface study, not live map imagery.
The ritual
FEET FLY keeps the controls small so the descent can stay large.
Search Apple Maps or tap a visible point. No device-location permission is requested.
Enter feet or kilometres, then start from a familiar preset — 1 km, 10,000 ft, or Everest.
Altitude, speed, atmosphere, and camera perspective move together until touchdown.
The map is the stage
The scene uses Apple satellite imagery and available 3D elevation as context. The camera begins overhead, then eases toward the ground as the simulated altitude falls.
Under the hood
The model is intentionally legible: enough structure to make the journey interesting, never a claim of prediction.
9.80665 m/s²
A constant Earth-gravity baseline keeps the motion easy to follow.
e−h/H
Pressure and density follow illustrative exponential curves as altitude changes.
v2
Air resistance grows with velocity squared and opposes the descent.
FEET FLY does not model a person, equipment, terrain, weather, or safe procedures. Its imagery is atmospheric context, not real-world guidance.
