Interestingly enough there seemed to be a bit of banner coming through at the end when he was still the Hulk when he made a conscious decision to use the quinjet to get away from it all.
Yeah, I think the most telling thing here is that Hulk closed the rear door and turned off the comms.
Hulk.
Pushed buttons.
Not smashing them.
Clearly there's been a psychological shift in the Hulk-to-Banner ratio.
IDK - I think it was there in the first film, in the scene where one of the Chitari 'Dragons' is flying towards them and Captain America says:
"Dr. Banner, now might be a good time for you to get angry..."
And Banner relies:
"That's my secret, Cap. I'm always angry..."
And he then runs down the street turning into the Hulk as he goes and does a punch to the 'Dragon'.

IMO - that scene to me showed Banner (at least in the first film) had more 'control' over the Hulk then he let on to those around him.
And again, while I actually liked this second film over the first in a lot of ways, I was (and have been) disappointed that the writers seem to keep riding the line between:
Does 'the Hulk' have his own unique personality and is just letting people think he's a monster?
and
The Hulk is essentially mindless, driven by instinct and influenced by banners 'motivations' (for want of a better term) as he changes?
In the first film they did give the Hulk some lines that reinforced the former as a possibility in the scene with Loki (after the Hulk smashes loki into the ground repeatedly - and IMO one of the best scenes in that film) where the Hulk, walking away says, "Puny god."

In the second film, the Hulk himself had no lines that I could make out, and yeah, until the Quinjet scene where BW is saying they can't track the plane, the Hulk DOES push buttons to turn off the com-link, etc.
So yeah, I'm honestly disappointed that they really have yet to give 'the Hulk' a real personality (and my favorite is the Hulk personality from the VERY early Hulk comic appearances of the 1960ies where the Hulk WAS a separate yet still VERY intelligent personality (and it was the time where Banner just turned into the Hulk at night - anger had nothing to do with the change); so when it got close to sunrise - the Hulk would jump to the top of a high Mountain with no way down, or consume massive amounts of alcohol so that 'Banner' in effect was powerless to do anything until nightfall when the Hulk re-emerged.)
I'd like to see that done in a Marvel film myself...YMMV
