one of the passengers said that two stewardesses were ejected along with the tail. I guess their jump seats were on the bulkhead. That would likely be the two dead and being in the water would make sense given the point of impact.
Can't say until we see confirmation. A buddy of mine who was there told me he saw a body on the ground near the tail section, not in the water. That would account for one of the two reported dead. He was there walking in the debris field, and said it wasn't pleasant.
