So,after all this,how did they extract the aircraft from its predicament ?
Dont know how they did it in this case but the usual method is to lighten the aircraft as a much as possible, dig out the earth in front of the wheels and lay out steel planking and then tow it out. Afterwards you wash off and carry out detailed inspections of the gear assembles.
The whole procedure is detailed in the Manufacturers Aircraft Recovery Document - if you choose not to follow that and damage the aircraft then your arse ends up in a sling.
