Hi Sacajaweau - hope you are well !
I agree, if a fire, the plane wouldn’t have executed more turns over a course of several hours but we know it did. It’s been reported the last ping from the engines indicated normal altitude.
While the whole world is looking for planes and penguins in Antarctica, where did those pesky Iranian ships go after they cleared the Suez? Check out the graphic at link for suspected routes that could be taken by the Iranian destroyer and helicopter carrier supply ship (think: refueling). Their southern route, as charted, is rather interesting, wouldn’t you agree?

food for thought....
Ah. thanks. Yeah,I had forgotten about the Iranians and the speculation of what they are up to.
