http://spaceflightnow.com/delta/d364/status.html The fuel for this massive rocket is pure hydrogen and oxygen. Meaning it will make a contrail of pure water (no exhaust particulates required). It will be visible from all over Southern California, and maybe some of Nevada. Here's the last one from Orange County (south of LA) I'll post updates in this thread, and then see if there's any fallout from people spotting the trail, and thinking it's suspicious. [Update] Here's one of my better photos. More below.
