Yes, just thought you would be interested in this since there is so much speculation. This interview is the only thing I’ve heard from a guy who was actually there and can say what happened. If you read the comments at the site, it seems that the workers have all been slapped with injunctions to keep quiet.
Man, I hate to move into this territory, but (Devil’s Advocate here) could the worker have mistaken the “gas bubble” for a fire ball coming up from below?
Thing happened the day before Earth Day, right?
