Just did that, and it sank as you said.
I spent the last 45 minutes looking for the bomb explosive power table (not sure what you call it) that I remember from a while back with no luck. Looked on the trainers site and the help site to no avail. If I remember correctly it was a barred link on some page just couldn't find it. By the way it's not the table in the strategy guide under the strategic targets section, it's the table that listed the 1.719k value that Murder referred to.
Thanks,
