Sadly the only cure for heat haze is to be able to get closer to your subject. (Or move to a cool damp country like the UK
As I said before I feel the nose of the Alaska 737 is affected by heat haze and hence the shot is likely to be rejected. This problem can't be fixed by editing.
Unfortunately given the camera you have I doubt that any of the shots you have shown in this thread can be brought up to the required standard. I think you are doing a very good job with the camera you have but it is always going to be difficult to get "action" shots accepted that were taken with a point and shoot especially at the lower end of the MP
I would suggest you keep trying with ground shots especially if you can get close enough to eliminate the heat haze. If you have access to any aviation museums or small GA
fields where you can get close to static aircraft you should be able to get shots that will be acceptable.
Once again, good luck.
One thorn of experience is worth a whole wilderness of warning.
