## What the aircraft actually flies over

From London the path crosses United Kingdom, then 101 km of open water.

The furthest the great circle gets from the equator is 53.4°N, 100% 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.

The heading barely moves: north-west out of London, north-west into Dublin. Over this distance the curve has too little room to bend the compass.

One economy seat on it is about 67 kg of CO₂e each way, counting non-CO₂ warming.
