http://en.wikipedia.org/wiki/CH-53
flew about 300 yards east at about 500 feet northbound and then directly overhead no more than 300 ft on the southbound return
had never seen one in flight and the sound is so different (from a huey or such)due to the number of rotor blades
other than that not much in the way of cool aircraft overhead--cept for the ships that hang out just south of here
