One of my contacts got a call from the Mouse about it. He (my contact) said its ok and I can continue my pursuit of this, but I am working on confirming
Perhaps this is my skepticism, but if "The Mouse", being Disney execs, said it's okay to pursue this, then it's probably not accurate. They aren't going to allow the inner workings of the ride or queue to be released this early by unofficial channels.
All artwork shows the only thing under the Falcon are the landing legs, and aerial shots show it's not attached to the building. With a space that small it's near impossible to fool people enough to think they entered the ramp and made their way into the cockpit while really entering the show building. I know Disney is good, but making us believe we are doing what's in the green line and somehow taking us the distance of the purple lines (especially the top-right table) doesn't work for me. You'd have to suspend a lot of disbelief for that, especially to the die-hard nerds that are pretty familiar with the layout of the Falcon.
Also, you said a few pages back that rumors were leading toward the outside Falcon being a photo op with your contact even showing you a photo of the non-functioning cockpit. THIS I can believe.
Neither of these 2018 Nearmap photos shows any indication there was any underground tunneling system being put into place:
This official picture Disney released shows no connection on the port side of the ship:
And this picture shows nothing on the starboard side:
Another nearmap that shows more completion of the frame than the one I inserted above. No visible connections between the framework and the show building:
The way I predict the queue will work is that you will be lead through a small hanger or cargo area to one of four cargo bay type doors with a screen above it similar to waiting for Star Tours. An animation will show the Falcon that's parked outside with an umbilical tube stretching out from the hanger to connect with the ship (probably on the port side), and the cargo bay door will open and you will be lead into the faux umbilical tube to a faux inside of the Falcon that isn't the prop outside, but one of 4 inside the building. We SAW in Yensid 55's videos of pieces of the inside of the Falcon being dropped into the show building. Not just the cockpit hallways, but the seats at the chess table and bed that Chewie laid in when he got injured in TFA. I don't have time to find and screen cap them, but they are there. After the ride, similar to the image you showed, we'll probably go back through a cargo tube to exit the ride thus preserving the illusion we were in the prop the whole time.
I admit, I'd love to be wrong on all of this and we enter the ride from the outdoor prop, but evidence leans more toward the outdoor Falcon prop NOT being the entrance to the ride.
