"Tmavomodrý svet" ("Dark Blue World")

[Franz von Werra]

Yesterday I acquired the DVD...I came, I saw it and I bought it.

But...I seem to recall that dinghies were usually linked to the pilot's chute harness by means of a line. Why is this detail omitted in the movie?

Maybe because a dinghy - an apparently minor object in the plot - was to evolve into the real prompter of the key fact of the movie?
