When I was a child, we had a LP record with four Superman stories.
My favorite was "City Under Siege," about a group of terrorists who threaten Metropolis with a homemade nuclear weapon. (The was also released as a 45-rpm single, with an attached comic in the album, but we didn't have that.)
The story seemed rather sophisticated, at least compared to typical media for young children. It describes nuclear bomb sizes measured in "kilotons," talks about Superman's flight approaching the speed of light, and mentions radioactive tracers used in hospitals. (That was the first time I, as a child, had ever heard of radioactive tracers for medical imaging.)
However, there was one bit of terminology that confused me as a kid, and I still don't know what it means. Here's the panel from the comic version of the story.
Lois Lane gets a call (staring at about 2:45 in the YouTube recording) from the leader of the terrorists, Trask, who tells her
We want ten billion... ten billion dollars in gold. It will be placed aboard a 747 jet airplane, fully fueled, in gander.
So what does "in gander" mean? As a child, I hypothesized that it might refer to some kind of aviation fuel, or to some location at the airport (presumably for easy takeoff). However, so far as I know, neither of these is correct. The meaning of "in gander" is still a mystery.
I have searched for an answer online several times, but I have never located anything satisfactory. However, I did just uncover a connection between the airport in Gander, Newfoundland and early experiments with in-flight refueling. This reference doesn't make any sense in the context of the Superman story, although it is at least related to the topic of aviation fuel. So the writer of that story may have misunderstood the meaning of "fueled in Gander" and inserted the phrase nonsensically into the story.
However, is there some other explanation of the "in gander" terminology that does make sense.
