Amazing day-out gentlemen. KERR (kinetic energy recovery rope), fellows in US call it 'yanker' would have been a helpful option before the things got really nasty. Being used specifically for mud, sand snow bogging recoveries where pulling, pushing, snatching & winching is not effective.
A few years back, I saw a similar recovery in Cholistan desert on the recce day of Jeep Rally couple of miles down the track. A vehicle was stuck down to belly with submerged diffs in a few feet long puddle due to a an overflowing water hole along the pipeline. The driver possibly tried to cool-off by driving thu it at quiet a speed though. By the time we reached that spot, they had tried double vehicle & a tractor for extraction. No movement of course.
Those who are familiar with 4x4 Rally scene, know the amazing gentleman in the Dodge. Ronnie Patel. With the help of KERR, the vehicle was pulled out @ of about an inch a minute :-#.
