What Fred Flinstone said.

I got one of the original USAF leather flight jackets, circa 1989. It is goat skin and I have never liked it. It will not stretch, has an ugly shine to it, and never gets the classic "worn-leather" look.

When I and my fellow USAF brethren would deploy to Incirlik Air Base, Turkey, almost everyone was going to Pop's shop to get their jackets modified. Pops would put in a liner, pockets, and modify the under-arm so you could actually lift your arm without the whole jacket moving with it.

It is interesting to see that 15 years later, Pops has gone from a one-store local-deal in the infamous "alley" outside the main gate, to a major suplier on the internet. It happened because he did good work for a fair price.

If you want a leather jacket, go with Pops, get a liner, and get calf-skin.
