Where did the idea come from? One way or another, we
always knew that
there would be a way to blame Microsoft.
At Foothill, along with some other stuff, I got a 1988 copy of Microsoft
Flight Simulator. The picture on the box is very stylized view of a
[small] jet flying in front of WTC! The text on the back of the box goes
on to suggest trying to fly your plane between the towers (they missed?)
Until just recently, either in the sim docs, or on the web page
associated with the sim, there is a table of famous landmarks
by GPS coordinates, in case you want to fly into one of them.
WTC is at the top of the list.
