I have been reading your analysis and from what you right, I gathered this much
Fokker 70 Specifications
Crew: two
Cruising speed: 845 km/h (525 mph)
Range: 3.410 km (2.119 miles)
Service ceiling: 11.000 m (36.089 ft)
With that little amount of flight endurance, that plane even after refueling in Dubai or wherever they wanted could have never made it to the US which is about
13,000km+. Maybe he was never coming after all and just went on a joy ride to hoodwink the populace.
Then you make a very important observation about the time difference and the change in attire. Why did he need to dress in a suit to return home after a 2 hour flight?
p/s I like your new and improved website.
