Test pilots work from very careful plans in order to gradually test the envelope of huge powerful machines filled with explosive fuels. Their test-engineers don't say "hey, we're going to do some stuff, but try not to kill anyone". Gross negligence. Perhaps you are simply unaware of how dangerous the situation was? Several experts (ex-truckers) have described how they have seen people killed in circumstances like this. If you're being intellectually honest, that should inform your responses.
