We also went, had a great time, loads to watch and eat. Spoilt a little by a certain aerobatic tit in his extra 300 showing off and laying smoke down on the taxiways and on the runway.
We were right behind him and the cockpit was filled with diesal fumes and we then had to sit and wait for a few minutes while the runway "IMC" cleared enough to take off, all while there were 40 or so aircraft trying to get out ahead of weather.
But otherwise a big thanks to Old Buckenham for a great day out.
