We've dug out a memory stick from a safety deposit box on the east coast of the US after following up on some leads over there, but all of the modified/access/creation timestamps have been wiped, meaning that we don't have even the slightest idea of when it was last used.
Said memory stick contains an array of incriminating files which prompt us to want to speak to whoever the memory stick belongs to.
Amongst the files on the drive, we have found a recording of a Boeing 737-800 aircraft taking off from some airport.
Can you find the latest possible date that the video was taken? This will help us to gain a ballpark idea of the age of the rest of the content on the seized memory stick. Note that the metadata of the video file itself won't be any use in this case.
Attempts are capped at 5, so refrain from completely guessing!
Expected flag format: DD/MM/YYYY
The video can be found here.
