This page from my Web site might be of interest to some of you. Click on the plane's 'Designation' for a link much more information about the plane, include date of First Flight. I found it interesting that a couple of the high numbers had first flights in late 1952. For those of you that havn't seen it before, my Web site's got a lot of airplane card info. on it.
