Tickle
The guys in the tower certainly did notice the nose wheel still up when Ansett's first try at an international flight from Sydney ended up as a wheels-up at KSA on return due to an engine failure in the B747.
They called the aircraft and advised them their nose wheel was not down just as it landed and was committed. Very embarrassing.
The fireies used to have a picture of it on the wall of their station in KSA.
