As Homelander and Queen Maeve reenter the airliner's cabin after the cockpit fight, there is no obvious sign that the aircraft is descending quickly, nor that there is an approximately 500 mph (800 km/h) frigid wind blast coming through the broken windshield behind them.
When Hughie and Annie are talking about their first kiss, Annie has already taken down the 4, 7, and 8 pins. When she goes to recover the spare, all 10 pins are back up.
Homelander enters Transoceanic Flight 37 using an over-wing exit door, which remains open during the initial fight with the hijackers. As the aircraft later descends after the cockpit fight, it encounters turbulence and the emergency oxygen masks deploy.
The emergency oxygen masks on commercial airliners are triggered by a loss of cabin pressure, not by a sudden descent or turbulence. The masks should have deployed the moment Homelander opened the door, which is left open for about 30 seconds, long enough to completely depressurize the cabin and cause most people (at least those without super abilities) to lose consciousness without supplemental oxygen.

It is stated that Transoceanic Flight 37 has 123 people on board and is flying from Paris to Chicago. All seats appear to be full. However, the aircraft in the exterior shots is a Boeing 737 MAX 8, which normally seats about 175 passengers in an all-economy configuration, and has inadequate range to make this flight with a full passenger load and adequate fuel reserves.
Frenchie makes reference to Jean-Paul Sartre but when he pronounces his surname, he says "Sartruh". A person who is French or fluent in the language would pronounce the name "Sart".
When Hughie and Annie are bowling, Annie throws her first ball and it goes into the gutter. The camera switches angles to show from behind the pins. Several pins fall on the left side of the rack. When Annie throws her second ball, all 10 pins are standing. When the ball goes into the gutter on the first throw and pin(s) fall, there is a 're-rack' to reset to 10 pins standing. This sequence was probably edited out for time ...
It is clear from both the on-screen map and a rudimentary knowledge of navigation that Transoceanic Flight 37 was flying towards northern Canada, and the closest land to the presumed crash site should be the coast of Newfoundland and Labrador. Despite this, the concentrated crash debris shortly makes landfall in New York City, many hundreds of miles to the south.
When Madelyn Stillwell shows Homelander and Queen Maeve the map of the route of Transoceanic Flight 37, the spot representing Chicago roughly corresponds with the actual location of Moosonee, Ontario, at the southern tip of James Bay in Canada. The Great Lakes are clearly visible on the map, but "Chicago" is nowhere near Lake Michigan.
