We debunked the Wiki/Emporis height of 395' a few months ago. I think it was Steely Dan that used Google Earth to map it at about 349'. RM_NM may have even confirmed with the Northwestern Mutual question submissions inbox, as well. Can't recall.
I don't recall, and may have missed that conversation. (Or my feeble old man brain just flat-out doesn't remember.) In any case, 345'-350' seems quite plausible. That said, I don't think I would necessarily trust the accuracy of an elevation pulled off of google earth any more than I would a listed height on Wiki or Emporis. The answer from NML, on the other hand, is a much more reputable source, as it is likely info pulled from record drawings. Other than personally field measuring, record drawings will be the next most reliable source of info! (If someone could only get their hands on record drawings of 100E ... conversation for a different thread!)
