major flaws. Consider the land operations of the SALV. You already know
that the terrain is hilly and the SALV be able to reach speeds of 35 mph.
Given these pieces of information, what do you think you need to consider
next?

(2) High face validity is probably a good thing to have in any experiment,
but this is not the point of external validity. Return to Page 67.
