35 objects very high up, all aligned perfectly in a row pointing ESE - WNW. First 3 or so were slightly leading the rest, which were in perfect spacing from the objects in front of or behind. After approximately 10 seconds of observation, the objects in front began rising and becoming harder to see, followed by all trailing objects in 'cascading' order, until none were visible. Observation conditions - traveling west AL hwy 68 on lookout mountain between friendship drive and Handy Mart. Thru my truck windshield traveling 60 mph. Windshield has many random bugs from 3 hr round trip commute. Could not pull out phone in time to take picture.
