The S3 should be more than capable of nice inflight pictures. I used to use a G5
and had no problem taking inflight, or any other types of pictures.
I don't know how experienced you are in photography, but if you aren't already I suggest you get comfortable using your camera's histogram function. Take a test picture, examine the histogram, and adjust your camera settings as necessary.
For example, an over-exposed image would have a histogram that is biased to the right. Try using a faster shutter speed, or adjusting your exposure compensation to help correct this.
