Let's Explore The Airport Demo: Room 7 Fail!

I noticed one room is used where Buzzy talks about showing the airplane in the demo version of The Airport. However, by entering room 7 in ScummVM's debugger, I could interact in the waiting room and its clickpoints that normally you can't do since you are forced to the first airplane room after Buzzy has finished talking in the waiting room. But unfortunately on entering the command it just takes me back to the start of the plane. However room 2 in Putt-Putt Saves the Zoo demo works. Any advice would be appreciated.
