I can only comment on the Delta DC-8 because I don't have any interest in military aviation at all.
I think the main problems are the grain throughout the sky and the very light (plain white) upper part of the fuselage. Additionally, it seems to be a bit oversharpened. As this shot is quite a bit below the current quality standards and there are already five shots of the exact aircraft in the database, you'll have to improve the quality to get it accepted. Please note that your shot is not
considered as rare because it would be the first approach shot in the database and because it is the only shot of a Delta DC-8 in your collection.
