When Alec is talking with Rizwan at the end, Rizwan's beer keeps changing between full and half full.
The plane that crashed had done so just after take-off, meaning it took off from Reagan National Airport in southern Arlington, VA. It would've been fully fueled. Yet the crash site is shown to be amongst a dense grove of trees with hardly any damage. A plane crashing with that much fuel would've created a massive fire. When Rizwan arrives on-scene, the firefighters are just handling some relatively small fires, and there's no fire damage to the forest floor.
Rizwan sees the plane hit a bridge, then crash. At the time, he was Uber-driving a passenger. When he then drives to the crash site, his passenger is not with him. Assuming that he dropped the passenger off first then headed to the crash site, there would have been a lot more police and fire personnel on-site. Also, a civilian would not have been allowed to get that close to a fresh crash site.
Lots of geographic errors: 1) The news announcer states that the plane hit Chain Bridge, "just miles outside of Washington, DC". Chain Bridge is actually completely inside DC, except for its southern end which is in Virginia. 2) The plane crashes in some area very near Chain Bridge. Its wreckage is shown in a dense forest. The area on either side of the Potomac River near Chain Bridge is heavily residential, with no such forested area. 3) The plot states that the pilot was trying for a water landing in the Potomac River. However, near Chain Bridge, the river is shallow with a very rocky bed. Crashing there would tear the plane apart just like hitting solid ground.
