Interesting update, that German "Dan Cooper" comic I posted was printed as part of a German language only series from 1981-83.
I discovered that the story for the German series with the jumpers via the aft/tail door of a passenger jet first appeared in 1970 in a Tintin magazine. BEFORE the hijacking.
I think I have identified and found a copy of that Tintin (Belgian/French) magazine from 1970 and have ordered it. It will be interesting to see if the 1970 original version has any reference or images of parachuting from the aft/tail of the passenger jet or if that was added after the hijacking in the updated German re-release.
I think Snow already found that Dan Cooper was published in Tintin in 1970 BEFORE the hijacking ?
The point is finer,
yes, we know the "Dan Cooper" character goes back to the 1950's in Tintin.. a recurring character.
The very common Dan Cooper cover (L'affaire Minos) we see of him parachuting was published in 1974 and again later but no passenger jet with the aft/rear door open. This was problematic as it came out after the hijacking.
What I am specifically looking for is the first publication date of the "Dan Cooper" STORY referencing Dan Cooper
jumping from a passenger jet using the aft/rear door..
That appears to be in 1970, and I think the story is spread across 2 issues, another in early 1971.
The cover pic for the RARE German series is
amazing as it shows a passenger jet aft/rear open, that particular story first appeared in 1970-71 in Tintin. I have never seen that cover pic before,
Was jumping from the aft/rear depicted in the 1970-71 original version or was it added to the German re-release after the hijacking?
I am going to find out.. sometimes re-releases are tweaked??
I also found out that many Tintin mags were translated to english by outside publishing houses, I haven't found this one yet though.
