Car jacking question

[Mark_T]

My daughter's boyfriend (usually referred to simply as "the lout") was changing the drop links on his dad's Caravan earlier this week.

It was classic:
-van lifted using factory jack and no supplementary support like ramps or jack stands. Didn't even slide the wheel underneath the vehicle as a "just in case"
-wheels not chocked because the emergency brake was set. Unfortunately nobody told him the ebrake didn't work.
-he was sitting in the wheel well doing the work

When the van rolled off the jack the brake rotor came down on his foot. He was lucky that he was working on gravel and not concrete. He was lucky that his dad was there and strong enough to lift the corner of the van enough for him to pull his foot out from under the rotor. He was lucky he just fractured a couple of bones.
