Coming back from an unsuccessful trip to Pitsford Reservoir for a Corys Shearwater we stopped off at the impressive Cardington Hangars to see Airlander 10 the worlds biggest airliner. It is 92 metres long and weighs 20 tonnes. A few days later it broke free from its mooring and crashed into a field injuring two people. Cardington hangars are massive and can be seen from some distance when driving on the A421 near Bedford.
