You need to go to bed. I've read posts from you before, and read your work about the XB-70. You do a great job and are normally a coherent writer. Tonight, it appears you have been drinking. When you sober up you might want to reflect on the fact that people who don't even know you can tell over the internet that you've been drinking. What do you suppose people actually in your presence are thinking? Your research and writing ability are too good to drown in a booze bottle.
