De-Boarding Again!

They are de-planing us again! Apparently maintenance doesn't have the part they need or something or other. (Which makes me wonder why they reboard?) They've been very vague about details and are saying the flight hasn't been officially cancelled -- yet...

Lots of passengers, including the guy who was sitting next to me never came back on. Don't know if that's because they found better alternatives, got frustrated, or simply didn't realize we were reboarding?
