I guess it also depends on your definition of “leave Earth”. If you’re in orbit, you’re still kind of tethered to Earth. Quickest way to leave the gravity well is straight up, although escape velocity in most directions will get you there.

It’s a major enough speed boost that it’s cheaper to launch rockets from the equator than anywhere on the European mainland.

Actually, you go up. The earth rotates beneath you, turning your up into sideways.
E: then of course you have to turn east

You’re right: it’s the half-baked nature of your ideas which is revealing, not the brevity. The brevity is a mercy.

Inchoate ideas, articulated incoherently. Yet implying the inclusion of an incessant ideology.
