>>> We also saw a really cool Apache helicopter taking off
You should live around here, Sherr. There are 5 full squadrons operating Apaches just down the road from me, at Wattisham Airfield (which Wikipedia describes as " the biggest centralised operational Army Airfield in the UK").
We see, and hear, rather too many of the damned things, especially when they're flying night exercises. It's not easy to sleep when there's an Apache chopper repeatedly flying VERY low circuits over your house from mid-evening until 3.30 in the morning, as happened recently!
Oh, how we long for the olden days, when Wattisham was an RAF base and we had the roar of Phantom jets flying in and out. They were far better!
