400 feet? more like metres, & big chunks of insulating foam fell off, I fear for those guys, they rushed the launch, admitting that there were still design faults, for chrisakes, my theory, it was idiot Bush's idea, after days of delay, his only thought was, duh, "hey, fellow Americans, it's independence day now, launch quickly, launch right now, we have to celebrate, dammit, have you no pride??"
