An easter-egg in Firefly's pilot episode reveals that it takes place in the same universe as the Alien series. It appears the anti-aircraft cannon Mal uses to shoot down an Alliance fighter was manufactured by Weyland-Yutani Corp.
So does this mean Weyland-Yutani provided the Browncoats with weapons to fight the Alliance? Whose side do you think they were on in the Unification War?
If the text is too small:
"And now a readin' of this week's construction casualties. Hartnell, W. Troughton, P. Pertwee, J. Baker, T. Now a moment of silence for the workers lost - alright, that was it. Back to work!"
