Fortunately all were alright. Apparently they were under the glide-slope but could not see because of low clouds. After this missed approach, the airport closed until the clouds lifted and the plane did make a good(ish) landing.

This is why people need to look both ways at a railroad crossing. At least it was a trailer that got hit and no one was injured, but another few seconds and the car behind the truck would be filled with human pulp instead of a human sitting in their own feces and urine**.
