I was there. Probably one of the more junior officers there; another being my oppo. Two of us EngO students from M&S UAS had been sent on a 4-week summer detactment to RAF Binbrook - where it turned out that OC Eng Wg and OC EES, both of whom had a pair of tickets and each of whom had a young adult daughter, could not go - so us two lads agreed to to escort the two daughters. Happy days.
