It just goes to show you that arguing out this stuff is pointless - 12-18 months ago, so many people on here were swearing that it was SO obvious that the submerged x-wing was an inoperable wreck, as a way to explain why Luke couldn't go to Crait physically, thereby having to do the force holo projection gag.
I created this pic to show how the artwork and what was onscreen in TLJ differed significantly, yet everyone pointed to that source book showing the x-wing's wing being used as Luke's door! And people were mockingly saying "oh, don't tell me - you expected Luke to put his hand out and raise the x-wing - just like Yoda and as the perfect mentor/jedi-megastar (ie and go save the day on Crait)... right?
"
And then, in TROS.... he does just EXACTLY that.
As I said a few days ago, I laughed so hard during TROS when that x-wing wasn't even this water logged, barely operable ship - it was perfect, had a helmet all ready, fueled to fly a gazillion miles and its tracking beacon working at 100%.
