Crystal then left the area (perhaps Fitzgerald said they were OK) but later called Crystal for assistance and turn 3 was made as Crystal tried to return to the area of the collision and was again told that Fitzgerald was OK and didn't need anything which led to turn 4 as Crystal again began leaving the area toward Japan.
That's the only thing I can think of that would explain that big loop and aiming at a return to the area of the first turn.
I don’t know. I’m just going by the blue chart track, pure speculation at this point.
