For what it's worth, I've got heights for the Sears Tower and the Hancock in Chicago. Both buildings have a main roof level and a secondary "mechanical penthouse" roof level above it creating a sort of head-and-shoulders look. For the Sears, I find that the main roof level is 1450 feet above the level of Lake Michigan. For the Hancock, the main roof level is 1122 feet above the lake. I estimate observational errors of +/-2 feet. For both buildings, I estimate that the higher, smaller roof is 20 feet above the main roof. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
