New account after being inactive for years (was seraphina).
One for the pilots - how do you account for the Earth’s rotation? For example, flying LHR to (eg) Johannesburg, if you took off, pointed the plane at JNB, then as the Earth turns, you’d surely have to keep adjusting the direction the plane is pointing in, as the Earth’s rotation keeps on moving JNB relative to the plane. I suspect this is one of those things that automagically sorts itself out (something something airspeed vs ground speed??) but my brain can’t figure it out!
