That girl on the right in the first picture, we need more photos of her!
Been looking but so far only found censored videos. Oh and that video you linked too, it's not the same roller coaster. That's the one from a few years ago done in Alton Towers. The photos are from the latest record attempt at Adventure Island in Southend.
