the simple formula 'E= M * V^2',

Typo. Actually, the formula is 'E=.5M * V^2'
but the important thing is
the relationship between mass and velocity. Double
the mass of your glider and
you 'only' double the landing energy, double your speed
and you quadruple the
energy!

Thank you for that simple statement. It is clear and
concise, the way our instructions should be. Many of
us and many, many more do not 'read' formulae. I have
no personal knowledge of the meaning of the '^' symbol
in the above equation, but I know very well the truth
of what it purports to state.
