Funny jokeAn airline pilot wrote that on this
particular flight he had hammered his ship into the runway really hard.
The airline had a policy, which required the first officer to stand at
the door while the passengers exited, give a smile, and a "Thanks
for
flying XYZ airline." He said that in light of his bad landing, he
had a
hard time looking the passengers in the eye, thinking that
someone
would have a smart comment, but no one seemed
annoyed.
Finally everyone had gotten off except for one little old lady walking
with a cane. She approached and asked, conspiratorially, "Sonny,
mind
if I ask you a question?"
"Why no Ma'am, what is
it?"
"Did we land or were we shot down?"
