Question 1

• When an airplane flies directly into the wind, is
  the speed of the airplane across the ground more,
  less, or unaffected?

• Answer Less speed. In fact, if the airplane's
  speed matches wind speed, the airplane would stay
  in one place (like a bird often does when it
  faces the wind) .

Question 2

• When an airplane flies directly with the wind, so
  the wind comes from behind, is the speed of the
  airplane across the ground more, less, or
  unaffected?

• Answer It is more.

Question 3

• When an airplane flies in a cross wind, so its
  nose is pointing at right angles to the wind, is
  the speed of the airplane across the ground more,
  less, or unaffected?

• Answer It is more! How much more and in what
  direction is found by vectors!
