Revised January 31, 2017
Except for those navigators whose dates are shown in blue, numbers 32 through 48 were employed all of/part of 1953 and 1954. However, no seniority list or date of hire is available. Their names were listed on company "personnel distribution" sheets. Some navigators who left the company prior to 1953 or 1954 do not appear on any available seniority list. As they become known through examination of Seaboard newsletters and online crew manifests, they are added with blue dates indicating that the actual date of hire is unknown. The blue date is that of the earliest manifest found as yet listing that person as a Seaboard crewmember or a mention in a newsletter.
Navigators for whom seniority number is not known are listed at bottom of list. (119 - 130).
The era of navigators ended at Seaboard in late 1970 when the entire fleet was equipped with Inertial Navigation Systems.
