An aircraft company discovered that it was cheaper to fly its planes
|
||
with less fuel on board. The planes would be lighter and use less fuel
|
||
and money was saved. On rare occasions however the amount of fuel was
|
||
insufficient, and the plane would crash. This problem was solved by
|
||
the engineers of the company by the development of a special OOF
|
||
(out-of-fuel) mechanism. In emergency cases a passenger was selected
|
||
and thrown out of the plane. (When necessary, the procedure was
|
||
repeated.) A large body of theory was developed and many publications
|
||
were devoted to the problem of properly selecting the victim to be
|
||
ejected. Should the victim be chosen at random? Or should one choose
|
||
the heaviest person? Or the oldest? Should passengers pay in order not
|
||
to be ejected, so that the victim would be the poorest on board? And
|
||
if for example the heaviest person was chosen, should there be a
|
||
special exception in case that was the pilot? Should first class
|
||
passengers be exempted? Now that the OOF mechanism existed, it would
|
||
be activated every now and then, and eject passengers even when there
|
||
was no fuel shortage. The engineers are still studying precisely how
|
||
this malfunction is caused.
