Regarding the Swedes shooting at US planes.

I have read something like this:

An American bomber, damaged efter bombing Berlin, tries to make it to Sweden. When approaching swedish territory, they are contacted from the ground:

"You are now enterring swedish territory which is prohibited"
The captain answered " Yes we know"

"If you enter, we have to shoot you down"
Captain; "Yes we know"

The swedes started to shoot - then suddenly they could hear the captain saying: "You are shooting far behind us"
The swedes answered: "Yes we know"

True or not?? It was written in a book som 60 years ago.
