I have to echo the aargh!
As for the bombs, I believe this was a test of Superman. I think this was Trask. He didn't know about his enhanced vision capabilities and this was to be a general test of his ability to overcome a major disaster. Instead it worked out almost as well. Trask and the rest of the world learned more about his abilities.
As for Lois, I'm curious how that will go. He needs to find some way to tell her the truth ASAP. I hope this isn't going to be a long string of "can't quite tell her" situations. That would change my aargh to an AAAARRGGH!!!
