Unlimited first class flying with the Unlimited AAirpass
In 1981, American Airlines introduced a pass that allowed unlimited first class flying around the world: the Unlimited AAirpass. It cost $250,000 and for an additional $150,000 you could take an extra passenger. The pass was discontinued after a few pass owners made a lot of use of their pass and the airline began to make huge losses.
Experiment with music-making road stopped after one day
If a motorist drove the permitted speed on the N357 in Friesland, the Frisian National Anthem would be played at the correct speed. Unfortunately, the experiment was stopped after one day. Motorists drove extra fast to see how fast the music could be played. In addition, local residents heard all sorts of noises mixed up; the road not only caused dangerous situations, but also inconvenience.
