According to the story, the bus driver kept the doors closed. He was asked why he didn't open the doors to let the passengers get off. His reply was that he was trying to prevent new victims from getting on the bus so they could join in the inevitable lawsuit.

Back in the 1960s when they were static testing the Saturn V first stages* at Marshall Space Flight Center in Huntsville (my hometown), people were claiming that the tests were breaking their windows. They made these claims even when no tests had taken place. Any broken window was automatically blamed on engine testing.

*Back in 1966 or 1967, I got to watch one of those tests from 3 miles away. I was about 9 years old. It was very impressive, both the noise and the flames that went hundreds of feet into the sky. Very, very cool.
