Greetings, I live 5 miles south of BWI Airport in Maryland. I have outside today enjoying the perfect weather. 

 I have noticed about every 5 minutes, very large gas powered aircraft flying over about  cloud height, 10,000 feet? This has been happening for a few hours now. It may be two planes circling over but I only spot and hear them going due north. Has anybody noticed this. Could
they be B-52's?

 What frequency would I use to try and hear them?
