>between 82 and 256 feet (between 25 and 78 meters)
>23,179 miles per hour (37,303 km/h)

If that hit in near a populated area it would have been devastating.  

Edit:

You escape the air blast by being shock melted.

I love reddit.

If you are shock melted, you escape the air blast, AND you don't have to worry about the ear drum rupture. Seems like a good option.  :D
