talking about towbars..
In the old KUL airport in Subang, 747s would be parked right up against the terminal...this was the only way they could squeeze a big jet in the space available.
Trouble was if the pilot missed the stop-bar and overshot by a feet or two the tug would only be able to squeeze into the space available with great difficulty...
Did you know that a 747 has tow points behind the nose wheel as well ? and the standard towbar will fit? Had to use this method once when the pilot missed by more than a few feet.. (lights were kaput).
