Turning around was not only a VC10 problem. Uncle Sam sent a bomb disposal team to the Solomon Islands to sort out some mustard gas bombs left behind by someone after the 2nd WW. They, every bit of a dozen or so, came courtesy of a C5. When he taxiied in they followed the marshaller and when they stopped they found out that they could not turn it around.
There weren't any tow trucks or vehicles big enough to move it. Washington refused permission for them to use reverse thrust to reposition it so in the end a C17 had to fly in with a tow truck so they could get it airborne again.
