Sorry, I was doing meters/second and didn't give units like I meant to. 1000 comes out to 2236 mph, a bit more than your source which claims 2188. Maybe the 2236 wasn't quite official for some reason. But, we basicaly agree here. And yes, I didn't consider rocket planes, and didn't consider the shuttle, etc. Dan M. -------------------------------------------------------------------- mail2web.com - Microsoft® Exchange solutions from a leading provider - http://link.mail2web.com/Business/Exchange _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
