## What the aircraft actually flies over

From London the path crosses United Kingdom, then 125 km of open water, then Belgium, then Germany, then Czechia.

The furthest the great circle gets from the equator is 51.5°N, 0% of the way along.

Holding a single compass bearing the whole way would cover almost exactly the same ground, so on this route the flat map and the globe agree.

Leaving London the aircraft points east (93°); it arrives into Prague heading east (104°). That is 11° of drift without a single turn — the compass moves because the path is a curve on a sphere, not because the aircraft does.

One economy seat on it is about 155 kg of CO₂e each way, counting non-CO₂ warming.
