Thanks for your analysis.
Beijing Biden is NOT the president; he just plays one on TV.
If you go to YouTube and search “Biden air force one” you can watch that whole video. Lots of unusual stuff going on. Starts with the train of Suburbans racing to the plane, what’s the hurry? After biden stumbles aboard, that door, the L2, is immediately closed and the stair truck backed away. What’s the hurry? Then as the people are still boarding at the back door, the L3, the pilots start the right engine. What’s the hurry? A running jet engine with a boarding door open makes for a lot of noise inside the cabin, even on opposite side of the A/C. When the aft stair truck backs away, the pilots start the left engine and the plane taxis away immediately. What’s the hurry? Seems to me like someone is trying to make a quick exit.
