Hi Air-bus,
I was in the DC-6 which arrived at CVT just as the Metro was running up on the south apron. We parked on stand 1 (right next to it).
Now you mention it, I do recall the tower having some problem's trying to call the Metro - the engines were running, but they didn't reply to any attempts from the tower to contact them - the crew were clearly distracted by something.
I do remember seeing the Metro F/O in what looked like a very compromising position!!!!! - no wonder why he got hurt. I hope he's OK.
