RiffRaff thanks for the condolences. In my "professional" (and I use that term loosely) opinion the air jack's might have helped. Since I don't have pictures I'll try to describe what went on: The ditch was about three to four feet deep and probably a couple of feet across with square sides. When Vicki fell in the entire passenger side was resting on the opposite side of the ditch. Standing in front of her she was sitting at about a 45 degree angle (side to side) with the passenger side below the level of the road (like she had just sunken into the road).
I don't think that there was any room to put, even, a deflated bag between the VX and the side of the ditch and that would have just pushed her toward the near side of the ditch, but I guess that they would have protected her as we pulled her out. If we had put the bags under the VX then the passenger side would have been suspended by the bags. I don't know how tough those bags are, but I don't think that they would have been able to roll because they would have been wedged in the ditch. I suppose, if the bags are tough enough, we could have dragged her out across the bags, but we might have punctured them as the VX was scraped across them.
