The other day I found myself called upon to try and recover a 3.5T minibus that had both n/s wheels in the grass verge. Rear end down to the axle, resting on bodywork.
We dug out the ground a bit around the buried rear tyre. Then hooked it up with my 5T tow strap looped around front axle and back to rear eye with shackle. I took the strain... but even with passengers pushing the bus wouldn’t budge.
After several failed attempts I went for broke, gave it a foot of slack and went for a snatch recovery. Out of the verge it came! I was aware of potential damage to strap, etc. but thankfully all was ok.
But subsequently I have wondered if I’d given it more of a run up, with a harder jerk, could I have set off the airbags? Anyone ever triggered theirs like that?

Never heard of it, done and watched loads of snatch recoveries and never seen it.
Airbags are set off by either impact sensors or potentially angle sensors if a car senses a high speed roll over / flipAltox GSM FBH controller thread

I thought there was a minimum speed for the air bags to operate. 18 mph rings a bell.Disco 4

For the front airbag sensors it used to be the case that there was another sensor deeper in a car and the bumper ones had to show different readings to the deeper one to prove the car was crashing and crumpling before the airbags would fire.
Thanks for the replies guys. I was with this lot on the bus and I’m not planning to make a habit of being a Good Samaritan!

Not much good if someone smacks into the side, or front or back, of you if you’re sitting stationary at lights. I’d deffo expect the appropriate bags to fire if that happened.

My definition of snatch is obviously different to yours - this thread is an utter disappointment...
