I don't think so, Paul. According to my JP, (and all such planes I've seen so far), aircraft registered in Oman are A4O-** (and that's an "O" after the "4", not a zero - another frequent mistake). God only knows why, as A4-*** is not taken by any other country.
Just to back up what Andy said, sometimes it is not easy deciding what the problems are. They can be difficult to define, and not part of the 20 or so "standard" reasons.For example, a pic that is soft, but not so much as to be blury, poorly lit, and photographed with a digital camera with it's color balance, black point and white point all poorly set. We actually get stuff like this quite often (I guess a lot of folks buy an expensive digital camera and don't bother to read about all the little adjustments you can make). Imagine the result. How do you define it? Your first reaction might be "Yuk!" (the subject of another thread). But it might be dificult for you to break down the problem, as you don't know what the photographer did. Maybe, his black/white point etc. is fine, but he has a shitty monitor and he screwed it up in post-production. So the cop-out might be a "badscan" rejection.
The only thing you should feel when shooting a terrorist: Recoil.
