They just showed an outdoor shot of the shuttle-saw some lightening.

It also looks like they are burning off some kind fuel? Anybody know what that is?

I saw that “burn-off” too.

It puzzled me.

Looked like a refinery stack around Port Linden.

They always burn off liquid hydrogen during fueling. Looks a little more spectacular at night.

As for as what a Phase II lightning alert means, this is direct from a NASA paper on lightning at KSC....

KSC pioneered a two-phase lightning warning policy. In Phase I, an Advisory is issued that lightning is forecast within five miles of the designated site within 30 minutes of the effective time of the Advisory. The 30-minute warning gives personnel in unprotected areas time to get to protective shelter and gives personnel working on lightning sensitive tasks time to secure operations in a safe and orderly manner. A Phase II Warning is issued when lightning is imminent or occurring within five miles of the designated site. All lightning-sensitive operations are terminated until the Phase II Warning is lifted. This twophase policy provides adequate lead time for sensitive operations without shutting down less sensitive operations until the hazard becomes immediate.
