Perhaps I was referring to the fact that they may have been trying to build
larger ion engines for space travel? I know that these engines are a
defininte possibility and I apologize for my error, David.

| Wrong! Ion rockets are in use now, and have been for 30 years. They're just not big enough to for sub-orbital work. See (URL) Drew ----- Original Message ----- From: "Kyle D.
