Factual error: The helicopter used during the exchange is a Mi2, which has not been in service with the Russians since the 1970s.
Factual error: When Dominica is tasked with swapping Intelligence using a laptop in the hotel, she is using floppy discs which is highly unlikely in the realm of international espionage. Not only do they not hold enough info at only 1.44MB each, but laptops have not had floppy drives for quite some years and this movie is supposed to take place in 2017.
Factual error: In two shots during the Heathrow sequence, a CGI airplane is seen taking off in the background. The airplane is depicted as a British Airways 747-8 Intercontinental. However, BA has never flown this type. They fly the older 747-400, which is distinguishable from the 747-8 by its vertical winglets. The newer type features blended wingtips.
