I do not think the Concorde INS had a data transfer unit for route planning, but it could have.
Even the early F-16 in 1979 had no such doofer. They came about in early-mid 80's. The Shuttle probably had data transfer cartridge that the crew could use, otherwise previous platforms prolly had their stuff loaded via a hardwire connection to another computer or via a data link RF system, as we did with Apollo.
In late 60's and until early 80's, we high tech pilots and navs would type in the the stuff!! 'course, the A-7D had the projected map and we could slew it around and enter coordinates using it without having to type. That was late 60's, and nobody else had that until the 80's.
That's what Gums remembers.
