There's a lot different schools of thought out there.
Normally, people begin with learning takeoffs and landings until they don't damage the aircraft anymore. Then they move on to using the weapons on ground targets and later on air-to-air combat.
Then we have the nerds: They read up on everything and THEN perform the above and stay with that for the rest of their lives, never pushing the envelope.
And finally, the whackos: Never read up on nothing, just set the controls and start practicing carrier landings! Yeah, I'm one of those. When I get a new aircraft I always start with carrier landings. It's the best way to learn piloting a new aircraft, how it behaves at low speed, how things like gears, flaps and airbrakes work and what not. After that, I go straight into a shooting war. Cause there's nothing like combat ;)
