Ouch, that's gotta hurt.. I'm not saying I disagree, but I do wonder if a project is going "right" only when it starts to hit excruciatingly long shifts and burns workforce like coals - especially if it is expected to safely carry humans to the Moon. I think it's more likely a sign of doing something that wasn't planned and budgeted properly (which may certainly be because it simply had never been done before - so it will often correlate with innovative projects). If you worry about your workforce being motivated, transparently tying compensation to company success does wonders.
