This is so awesome, I live on the 9th floor of a highrise and they're praticing . . . which means I am getting an airshow from my living room They are flying so low . . . I can make out every detail on these planes. Some F15's are doing formation runs around the city right now . . . they look so graceful but when you do the math they are going mind boggling fast . . . from behind the sears tower to in front of a highrise I know is about 2 miles away in something like 15 seconds (that's about a mile every 2 seconds . . .)
