Or maybe they just don't see patriotism as incompatible with that view.

I'm pretty unpatriotic, but I still recognize that people can be patriotic and aim for the advancement of all humanity.

I would be hesitant to make assumptions on how SpaceX employees feel about this accomplishment as it relates to human advancement based on a simple three letter chant that is quite common in the US.

I can certainly understand how those from other countries, particularly Europe, might view the USA chants as over the top nationalism, but I think it's a stretch to assume that those taking part in it somehow view today’s accomplishments as solely the purview of Americans.

I was born in Eastern Europe and while I immigrated to the US at an early age, I have at times felt uncomfortable by the more visible aspects of American patriotism. Since it was brought up in a post above, I found the widespread celebrations of UBL’s death to be distasteful and jingoistic, and this is coming from someone who has deployed to Afghanistan and Iraq multiple times. I too feel that it can, in certain contexts, come off as overly nationalistic. Context is, as usual, important though, and in this context I view the SpaceX USA chants as pretty harmless.

I also find the insinuation that the employees taking part in these chants are guilty of nationalistic fervor to be insulting. There are many employees here, myself included, who didn’t have the good grace to be born in the US but have nonetheless adopted America as our homes and are now allowed to work on some of the coolest space launch vehicles in existence. The fact that some might express themselves in this manner doesn’t bother me, even if it isn’t something I would do myself. I for one don’t partake in the USA chants, although this arguably has as much to do with my relatively low key personality as it does with a conscious choice to refrain from outward shows of patriotism. I’m the kind of person that would politely clap at a touchdown or slam dunk rather than yell and cheer. One of my supervisors however, a Canadian citizen and US permanent resident, has a much more boisterous personality than I do and always joins in these chants. I know one or two Brits here who do as well.

It’s also important to understand the atmosphere during these launches. SpaceX isn’t exactly the easiest place to work, I just finished a 58 hour work week ending in a 12 hour shift before launch, I was not alone in this regard. People are tired, stressed, and somewhat on edge. While the live feed featuring the employees may look staged or choreographed, I can assure you that their reactions aren’t. The moments after a successful launch are an incredible relief and you can feel the energy in the building. The excitement is infectious and if that boils over into chants of U-S-A then so be it.

I’m also not sure what could be done to prevent this from happening. Again, those from other countries might view these chants as strange, but they really are very innocuous here in the US. I don’t see it as overly nationalistic, but again, context is key. Even as someone who doesn’t actively take part in them, if we got word from above that these chants were no longer allowed or discouraged, I would be extraordinarily pissed. Employees are already sacrificing a lot for this mission, they don’t need their spontaneous celebrations micromanaged.

SpaceX is an American company, located within the borders of the US, staffed largely by US citizens or permanent residents, funded largely(exclusively?) by US taxpayers, investors and companies, relying primarily on a US educated workforce, and 60 years of American led R&D in space technology. If all of that culminates in a successful launch and first stage recovery on a freakin’ ship in the middle of the ocean, I for one, can certainly excuse the USA chants.

I hope that my post doesn't come across as overly defensive or sensitive, it has been a long week and I certainly may be guilty of being overly emotional, but it’s always somewhat disheartening to see a thread relating to a successful SpaceX mission turn into an admonishment of perceived American nationalism.
