Good luck getting enough helium.
I guess we could generate Hydrogen though, and make for a better flash when Ace Biden shoots at them.
Per Pentagon, it’s not balloons...still unidentified.

I’d think hydrogen would be a good choice. You’d need a thicker film for the envelope, but the hydrogen would give extra lift to compensate. And the extra thickness would provide more strength in case of over inflation or abrasion while launching.
