Missed my flight due to enormous delay at security

Lots of snow overnight in Cambridge. Got up really early and cleared 25 cm from my drive, and successfully set off in good time for London Stansted airport. Arrived in terminal just over 2 hours before flight. When straight to security to find an immense queue being supervised by heavily arms antiterrorist police. They were great at scaring the inevitable cheats and loud mouthed pax. Anyway it took us 1 hour and 45 minutes to get to the departure gate, by which time our flight had gone. First time for me of missing a flight. It cost 100 pounds to book the same flight for tomorrow and another 100 pounds to deal with the consequences like getting back home for the night. I do not think the Spanish owners of the British Airport Authority are very good. But to be fair, as one should be, the reason for the massive delay was that a lot of airport staff were unable to reach the airport at 0530 this morning because of the snow. I am filing under "life's little challenges".
