Same reason Brits drive on the wrong side of the road? You got me- wondered the same. Perhaps because the original Telegraph article was published at 6:30 AM BST on June 6, 2014 exactly 70 years later, and went back in time to the “launch” at 00:00 AM BST?
That would make sense from a “here’s what has happened already, if you had been there”. Why I put in a few “already happened” from the timeline.
