Vaughn,

You absolutely did make a valid and important point, one often neglected in
pilot training.

I was just poking fun because you mis-typed the formula, and said that:

Energy = Mass times ENERGY squared (emphasis added)

Isn't that Energy = 1/2M*V^2 ?
IOW Kinetic energy = one half the mass multiplied by the velocity
squared as shown in my physics books.

When of course you meant

Energy = Mass times VELOCITY squared (assuming by '=' you mean 'is
proportional to')

I can make that joke because I would never make a typogarphical error.

Yes, of course I meant (and should have said) kinetic energy. In
this case, the units are not terribly important because I was trying to
compare the relative magnitudes of the kinetic energies between two
landing speeds and show how a seemingly small difference in landing speed
makes a significant difference in kinetic energy. OK?
