Subject:     Space plane
Text:        I have heard that supposed "space plane prototype" that flew over 
California and Denmark, and a few other countries.  I read an article which 
said that it used an engine which ran on liquid methane.  Is this the same as 
methanol in cars?  Also, is this  plane's engine a Scramjet (what is this 
engine about?), or what?

Text:        Methane is a gas from the same "family" that includes butane, 
propane, octane, etc.  Methanol is an alcohol and a liquid at room 
temperature.  Liquid methane is cold methane.
