Chucky, that dark bleak place is an airbase somewhere in Lincolshire. And the lighter area in the photo was the 'suckers gap'* that came through about half an hour before another bout of rain.
Alienax, she has an absolutely huge wing area, just as well as she made a very nice umbrella when the rain returned. She was due to fly to Portrush, but the weather in the west of the UK was a bit 'unseasonal', and shes limited to day VFR* only.
*'Suckers gap' because only a 'sucker' would take off thinking they would get back to thier airfield in similar weather, chances are the gap woVFRuld close and you'd be lost in cloud with no sight of the ground.
*VFR = Visual Flight Rules, basically you must maintain sight of the ground and horizon at all times when airborne.
