Yes, they got new recruits later on in the series as a last ditch try to revive it.
Frankly, Silverhawks sucked.
Now, before I get crucified for that comment, let me explain. I used to think Silverhawks was incredible, best stuff around. Then I actually found a tape of it at Blockbusters, and happily took it home to watch.
Oh.
My.
God.
I did not realize how horribly bad this show was. It was a police show, through and through. They all had police officer values, the episodes revolved around things like breaking up gambling rings, while the chief was a classical chicago police chief.
Talk about being slapped in the face, it was pure rose tinted glasses, because Silverhawks, while having insanely cool potential, was horribly done, potential wasted.
