Birmingham was not meant to be a destination on my trip, but iven that the Cosford RAF Museum (click me) was definitely a destination for me. It was a pain to get to (had ot take a train to Stafford and an expensive uber to get there without wasting an extra 1H+), but it was definitely worth it, especially with the private 3H+ tour that I got, it was fantastic:

FOMO me, instead of spending more time in the museum, elected to take an uber that was driving by (they are rare in the area, so that was a stroke of luck), I decided to spend the rest of the day in Birmingham and go visit the Thinktank Science Museum (clickme), which actually was a fairly decent science museum:

I then had just a few minutes outside of the train station before catching a long and slow transcontinental train to Cambridge:
