Counting the smiliar objects in the image by cross correlation

Hi, I need count the planes in a airport image by cross correlation. There are smiliar 14 planes which these planes stay different ways or angles. Also some of them are bigger or smaller than my referance plane. So, I can find only max 5pcs planes by correlation, could you give me exact example?

How can i find all smiliar planes and to count 13-14pcs planes in the image? Could you show me which codes i have to do that by cross correlation?

My example image is here:
