@Fritz Yes, that is unfortunately true, but you have to keep in mind that there are literally hundreds of aeroplanes for FlightGear. Some of them aren't finished models, others were created more than a decade ago and therefore are not up to the standards of more actual planes, and others are simply unmaintained. It surprises me though that you point the DC-3 as one of such, as I thought it was a well maintained aircraft. Which bug is this you are talking about? You know, I am a developer of some aircraft and scenery textures myself and it's difficult to find time to go after every bug report. Also, sometimes some reports simply get forgotten/lost, which is a pity. In the case of our Cessna 172P, for instance, in more or less a year since our project of revamping the plane started we solved and closed 350 issues, but still have 78 opened. It always seem that for every issue you solve, two new ones are opened...
About the DC3, I know that Pattern has a fork of it which may (or may not) have this problem solved. I haven't compared his version to what is on FGADDON, but you can give it a try:

And last, but certainly not least, the amazing Space Shuttle Atlantis (see

Note that this list will surely leave lots of good planes unmentioned since it just reflects the planes I tried myself and from the top of my memory.
If anyone would be interested, I can also prepare a list of interesting airports and sceneries, since this also varies a lot in terms of quality.
Cheers,
