The purpose of my deliberately wrong idea was to elicit reactions from
the NG. Needless to say that I succeeded.
And it has been fruiful, because no participant realized before that,
in order to get a corrrect result, they had to take into account the
fact that the floor of the accelerating elevator was moving forward
during the time the signal was travelling down. So, they have learned
something.
