Creating more aircraft

[mkrwii]

Hello. I am sorry if I am posting this in the wrong forum, or if it has been dealt with before. If so, please just post a link to the answer. I have been fooling around the forum for a couple of hours now, and I am giving up.
I am very interested in planes, and I use them all of the time in TT, but to my big disappointment there are so few!
I was thinking about making a little patch for myself with a large number of planes available, using the old graphics over again, just to increase the feeling of realism. (adding commuter aircraft based on the DC-3 and the Viscount, adding more regional jets etc, as well as adding non-western planes)
So I downloaded the source, and found the engines-file, but I dont understand anything of it, exept the obvious. Does there exist any guides to the list of vehicles, or any program making it easy to add/remove vehicles(aircraft)?

I'll be very grateful if anyone could helps me!

/me points in the general direction of the PlaneSet.

Oh, thanks. It should have crossed my mind to check other forums than just the ones about OpenTTD.
Does anybody plan a smaller commuter like the DHC-6 or Dornier 228?
