I doubt that there is one person above who has ever recovered a heavy aircraft from soft ground, it usualy entails getting together lots of perforated steel planking, long steel cables, usualy two tugs and visiting parts of the Aircraft mantanance manual that you have never seen before. All that before you start digging ramps behind the wheels to drag the Aircraft out.
I was lucky in the fact that when I last got involved with an incident like this we just had to deal with the practical engineering aspects of moving the Aircraft, no doubt the guys who had to get this Aircraft off the grass also had to be dealing with the hiderance of elf & safety experts who’s Aircraft knowlage extends to being able to recognise one from their office window.
