HI George, I do not know how the American Airforce satelites orbit, but .... 1) Do they come over our country. 2) If They do, how far back can we get info regarding fire-balls. 3) Would the info be accessible to us? I would apreaciate such info. Thanx -- Bill Hollenbach ah52@solo.pipex.co.za 32:30.11 Lat. 19:15.21 Long Partner of the Cederberg Observatory
