I've seen guys show up at my field with a brand new trainer, and perform take off and landings with it the very first day out. It does happen. I've also seen guys take a lot longer. It depends on the person.

So I wouldn't automatically write off anyone who says they "soloed" right off as BS.

(keeping in mind that "soloed" varies a LOT in meaning. For many guys, being able to take off, fly around a little at random, and get the plane back is good enough. My club as a slightly higher standard than that, but it's really not a huge deal).

That doesn't mean that some folks on here aren't making up stories or whatever, they could be, I don't know. But I wouldn't worry about it either way.

If you're one of the guys who didn't pick it up so quickly, don't sweat it. Many very good pilots took a while to learn too.
