100# table, sitting on scale,
10# helicopter sitting on table..
Scale reads 110#, correct..
Heli lifts off and is hovering over table..
What does scale now read..?
Will read 110# ..
Just because the heli is not physically
on the table, the 'cushion of air',, is,,
on the table...
Now,, if ya fill those damn canneries up with helium, and the truck driver takes a dump.. THEN,, he might be within the load limit....
