Your trifling quibbles don't matter. It doesn't matter what you call it or how you implement it, my original point stands. The Dr. is suffering from a lack of imagination.
Trifling quibbles? It was "airtight gaps" that brought Challenger down and killed seven astronauts. If you intend to argue using words, at least learn their meanings.
You're the one who can't use words properly. A "gap" is a generic term, an "airtight gap" is a type of "gap."
You're quibbling about words, you're on the wrong side of the quibble, and on top of all that, you're not even dealing with the main point I brought up.
