The Nashville bomber was either very skilled or very lucky

The FBI analysts interviewed for this report seem to suggest that Warner s task was made even more difficult by the need to build a timer that would ignite the air and fuel mixture at precisely the right moment. But is that really true? Warner was sitting in the RV when it went off. If he was able to obtain some sort of piece of equipment to monitor the levels of gas in the back of the vehicle, he could have ignited the cloud manually when it reached the optimum level. That would also have allowed Warner to switch over from his recording warning of an imminent explosion to Petula Clark s 1964 song Downtown just as the gas levels were approaching the needed concentration. (That s still one of the weirdest parts of this story.)

I used to love that song when I was very young.
