Continuity mistake: The blue car gets pushed through multiple cars and is damaged. Shortly after in the same scene, the car magically appears undamaged.
Factual error: The sisters run out of fuel for the helicopter, which is then shown slamming down on the ground and essentially destroying itself. All helicopters are capable of autorotating safely to the ground in the event the engine(s) quit. Of course, that would not have been as dramatic. (01:05:15)
Suggested correction: You may have noticed the helicopter was severely damaged, it may not have any rotating capabilities left after the fuel was gone.
I did notice it, but it did not look that any damage would prevent it from autorotation.
Perhaps the sisters (not being experienced helicopter pilots) couldn't use the autorotation properly.
OK, while that may be a possibility, if they have a helicopter pilot's license they would have had to demonstrate autorotation as part of both the curriculum and the practical exam. But listen, it's just a movie. The way they did it makes it more dramatic.
Factual error: Melina tells Natasha that the only way to get past Dreykov's pheromone block is to sever her olfactory nerve. So Natasha smacks her head on a table to sever it, hits Dreykov, then later pops her apparently broken nose back into place. Not only was her nose visibly not broken, but the olfactory nerve is a direct extension of the brain, with projections passing through a key bone in the skull. Severing that nerve would involve brain damage, and traumatic damage to those structures capable of this would require surgical repair.
Other mistake: Black Widow and her sister steal a BMW. Getting away they damage the left rear quarter. A few cuts later they show the car again and it has no damage to the left rear quarter. (00:40:15)
Factual error: When they are getting on the plane, which supposedly takes place in 1995, Yelena can be seen holding a Twilight Sparkle My Little Pony toy. This character was not created until 2010. (00:07:02)
Factual error: When she looks at the football game in 1995, the referees are wearing black pants. Those pants were not used until the 2010s.
Continuity mistake: During the opening scene when the family is driving down the road, a newer McDonald's can be seen on the right-hand side.
Other mistake: During the opening scene when the family is driving down the road, various gas stations can be seen with prices typical for the era in the low single dollars. But during one brief shot through the rear glass, a modern price of nearly $2.50 is seen.
Continuity mistake: When the ordered helicopters get close, there is a set of iron stairs in one shot blocking the door. A split-second later, when the door closes the stairs are gone.
