There's some interesting speculation from tweeter-on-the-scene Greg Surratt, the South Carolina pastor and Royal Princess passenger who's been sharing mini-reports for the past few days.
From a Saturday morning tweet: "Heard from very good source cause of fire: fuel pump. Not as good a source: involved explosion. Several sources: we are very lucky."
Of course, it's way too early for Princess to issue an official cause for the fire.
Meanwhile, Cruise Critic readers continue to discuss the event on the message boards. You can join them here.
