Other mistake: Dom drives his Dodge Charger out of the Antonov's cargo hold - which is filled with, well, cargo - through the nose of the plane which was already on fire while he was still in it - and yet there isn't a single dent on his car before he loses control and rolls it.
Other mistake: When Hobbs and Letty jump from the plane they jump down to the car, but earlier when Shaw's girlfriend fell out of the door she was blown backwards, this should apply to Hobbs and Letty too.
Other mistake: Hobbs asks to see all footage from "in and around Waterloo station." The technician is then asked to "bring up cameras 58 through 62." 5 cameras to cover the entirety of that area is laughable.
Suggested correction: That's exactly the problem that Shaw is referring to, a member of his team installed the incorrect plug which caused a problem, i.e. a Spark Plug and not a Glow Plug (a simple thing, causing the problem), along with the 'good' being simple minded and causing the rest of Shaw's team a problem.
The glow plug isn't what causes combustion in a diesel like how a sparkplug does for gas. The wiring harness for a spark plug vs a glow plug is completely different and they aren't interchangeable. You can't just accidentally put a spark plug in a diesel, it doesn't work like that.
