I agree 100% with everything you just said, especially the part about BAC wanting STI but not vice versa.
And I agree that if STI walks away, this new airplane (FTU/WB) will crash into a mountain at some point. STI will be a major beneficiary of this tragedy.
Did you ever wonder if STI is doing all this just to make sure that FTU/WB is so committed to doing this transaction that they never consider backing out? I think it is a big win for STI either way it turns out.
