The linked article is all I know. They said it was on take off, and one bomb seems like a pretty light load out. I'm assuming that they were the Mk 82 or 84's and I don't have the faintest idea if those can be dropped inert. They did close down the freeway nearby to look for other explosives though, so it's possible.
