I agree with you, especially about Trump being a disaster to everything he touches, but getting this one thing right is ironic, because it's the one thing that probably doesn't matter at all.
Boeing is too-big-to-fail in the same way BofA is, it would never be allowed to go under. It's more properly seen as an essential part of the US Government's defense establishment, supplying government-supported jobs (150,000+) across the US and ensuring a strategically-important technologically advanced manufacturing ability.
Money is shoveled into Boeing in many ways, not least tax breaks and those under-scrutinized defense contracts. Whether or not Boeing makes money on Airforce One is probably most relevant to the shareholders who would like to get paid dividends on profits, not the actual future of Boeing. I would guess the money they lose on this contract will probably be replaced by new over-priced government contracts elsewhere.
