I have heard stories that allege Elvis is alive and well and

Ain't it the truth! Almost as bad as the stories that allege the Brits
are "athletic" because they keep thinking that 'soccer' is a sport.
What a bunch of weakass Euro-peons chasing a round ball
around. They should bend and submit to America like always,
since we have the sense to PICK THE DAMN BALL UP AND
THROW IT."

Alas, these are just fairy tales. They are full of errors and are
worse than useless.

Which has nothing to do with the Coanda effect or Henry Coanda's
work.

The Coanada theory of lift brings to mind a question asked
of me, more as a joke than a serious desire for knowledge, about
the truckload of birds approaching a weigh station and the driver
knowing the truck exceeded the legal limits.

As he approached the scales, the driver smacked the side of the
trailer violently with his hand, thereby scaring the birds into
flight and lightening the load as he rolled slowly over the scales,
smiling at the inspector as he was now below the maximum weight.

According to the "Coanda" believers, if the birds actually get their
lift from Bernoulli, then there would be no downward pressure change
and the truck would weigh the same.
