I hate to say it but when the big fish ate the little fish most of the people that did the reports and evaluations went the way of the dinosaurs and retired. If you have any gray-haired contacts you may be able to find out who actually gathered the data but I'm afraid that someone would take great umbrage if I put their names in this forum.
Suffice it to say that at least two of the TWA guys were still there as of five months ago.
