In 1998, a bubble litter of this type was transported, via a med-evac chopper that also carried five haz-mat suited paramedics and Doctor Ben Bronschweig, to the proximity of a cave in Blackwood County, North Texas, where the bubble litter was carried out of the helicopter, loaded with the paralyzed, infected body of Stevie Richardson and lifted back to the helicopter, passing Dr. Bronschweig on the way. The bubble litter, containing Stevie's body and accompanied by the paramedics, soon left the area, aboard the med-evac chopper.
