A good a reason as any to go back down to Tatooine! Of course, that's assuming the missiles are locked on with something like IR frequencies and not visible frequencies. Tatooine probably blocks all of the usual IR scanning due to how hot the planet is, but as we've literally seen before, it doesn't stop anyone from being able to just look in the distance. The question then becomes, is Jim feeling lucky enough to outrun some missiles and ditch the fighter before it's blown up?

I didn't like the weird red bit on the side of the TIE fighter before, but it's actually very helpful here. In small images like this, I can still make out the side that's red. That helps me figure out that while Poe and Finn are still flying away, the guns are able to fire in reverse, possibly even rotating to do so. That's another definite improvement over the Empire's fighters in terms of general usefulness. We haven't seen any interior gunnery positions like with the Millenium Falcon, but I'm picturing Finn sitting in something similar in the TIE now.
