whose ya daddy,
First of all, that is an awful lot foul language.
Secondly, one would think that an excercise would be done without jeopardizing others - much for the reason airline training is done in simulators.
Sort of for the same reason Few Cludy does not practice evacuating passengers on the runway.
And that police men practice shooting on targets - not people.
And that firemen don't put occupied buildings on fire to stay sharp.
I hope that you are getting the point here, whose ya daddy.
