Von Hapen finding the helicopter pilot and telephone operator?
In the film, it shows von Hapen walking purposefully through the courtyard and casting a glance at the unoccupied helicopter, in the middle of opening his holster to draw his Luger. The next time he's seen is entering the dining room, the same way Smith and Schaffer came, with his Luger drawn.
Since he came the same way they did, this would've taken him past the telephone office, where we know Smith and Schaffer left the dead bodies of the helicopter pilot and phone operator. I've seen a publicity still (?) of von Hapen exiting the telephone office with his Luger out, looking alarmed/angry. In Alistair MacClean's novel, he does indeed go into that room and find the pilot and operator (albeit alive and tied up, since the novel is less violent than the film) which is what confirms his suspicions something is up and that there are intruders.
So, is there a cut scene of von Hapen entering the office and finding the bodies before he goes to the dining hall?
