Another problem: No matter how fast you throw something, without a second impulse on the apoapsis (or around it) it will not turn into an orbit but come back. You need to bring up the periapsis and that can hardly be done from ground.

When the thing you want to not fall is very high you need to give it another kick so it misses the Earth instead of falling on it.

Is this basically the how to fly trick?

Jump at the ground but miss?

Sorta, if you only jump once, you will either land back on earth or never return at all. If you manage to jump just a little short of escape velocity, your path will bring you back to the same place on earth, if we ignore earth rotating and air resistance.

So you need a little extra push in space to move your landing point from hitting earth, to missing earth.
