ForkTailedDrKiller: Your story has obviously had more than the usual amount of embellishment with constant retelling.
There was no tradition of flying between the tower and its neighbouring hangar below the level of the Control Tower windows, they turned straight on track for New Caledonia.
The wire you refer to was not strung up for that purpose, it was an aerial.
The aerial did not have little plastic propellors on it, it was marked by small coloured triangular flags.
IF someone had flown between under that aerial in full afterburner they would have almost certainly collected the roof of the fire section or one of the adjacent Pohutekawa trees.
