Suction is not the opposite of pressure, suction doesn't really exist at
all, it is merely a term used to describe a lower pressure.


I'm going to gently disagree, Bryan.

If the pressure above the wing is below ambient, it sucks...

In a episode of _Star Trek:The Next Generation_ Riker, Data and
others are exploring a delelict. Riker, after listiening to a voice
recording
says that evidently one of the crew opened an airlock door and was
sucked outside into space. Data said, "Blown out". Riker asked,
"'What?". Data Replied "Blown out. They were blown out. It is a
common mistake."

Data was right.
