Well you certainly can produce airplane simulation. However this is much too long for a demo. IMHO the music is very dreary ansd slows down the video even further. After a minute I was done. Perhaps you should consider a faster paced action cut of music and quicker cuts of the various aircraft and locations. Think in terms of 'Top Gun".
Thanks, it's actually not a "Demo" in the terms we use here, but more of a sample we produced showing that we can create a reasonably good video from a low-end simulation. I understand your statement about the music, actually it does pick up substantially in the second half.
It IS a niche area and unless you were interested in aviation or flight simulation, I suspect that the avarage person would not watch the entire 6 min.
