'Thor: Ragnarok' set images reveal Mark Ruffalo turning into the Hulk and the Quinjet being built on location

New pictures have surfaced from the set of Taika Waititi's "Thor: Ragnarok," and it apparently shows Mark Ruffalo acting out a scene where Bruce Banner turns into the Hulk. What's more is that there seems to be an unfinished Quinjet being built on location.
On set images show Ruffalo sprawled on the ground surrounded by the camera crew. This is most likely a scene that will have him spazzing out and turning into the Hulk. Just last week, it was reported that Ruffalo has already wrapped up all of his work on set.
Could this mean that Ruffalo would only have a small amount of screentime, or is Banner going to spend most of his time onscreen as the Hulk?
The movie will be borrowing some elements from the comic "Planet Hulk," and it is possible that the movie will have a fully sentient Hulk walking and talking with the sound mind of Bruce Banner. The San Diego Comic-Con 2016 even featured an exhibit with the Hulk's gladiator armor from the set. Does Bruce transform and wear the armor, or does he wear that armor as the Hulk 24/7? Maybe conditions in an alien world will make it easier for Banner to stay as the Hulk.
The images of the Quinjet on set also give the audiences a clue on how the Hulk ran into Thor (Chris Hemsworth) in the movie. The last time audiences saw him was when he was flying off in the Quinjet in "Avengers: Age of Ultron." It's quite possible that the movie would cover what the Hulk went through the moment he decided to run away from the Avengers.
"Thor: Ragnarok" is currently filming in Australia and is set to be released in November 2017.
