Even if Supergirl loses half its viewers that is still going to make it the most watched show on CW. Just one third the viewers puts it above Arrow.
I hope it's not on Mondays at 8:00, to much competition and I want to watch Gotham same day again. So that's probably where CW will put it.
Plus Containment was cancelled so that frees up another hour.
Most shows have that it takes two keys to launch a missile. But it actually takes four keys. Specifically so they can't be hacked.
Per US Air Force Instruction (AFI) 91-104, "The Two-Person Concept" is designed to prevent accidental or malicious launch of nuclear weapons by a single individual.[1]
In the case of Minuteman missile launch crews, once a launch order is received, both operators must agree that it is valid by comparing the authorization code in the order against a Sealed Authenticator (a special sealed envelope which holds the code). These Sealed Authenticators are stored in a safe which has two separate locks. Each operator has the key to only one lock, so neither can open the safe alone. Also, each operator has one of two launch keys; once the order is verified, they must insert the keys in slots on the control panel and turn them simultaneously. A total of four keys are thus required to initiate a launch. For additional protection, the missile crew in another launch control center must do the same for the missiles to be launched. As a further precaution, the slots for the two launch keys are positioned far enough apart to make it impossible for one operator to reach both of them at once.
Arrow was totally bogus. On Supergirl Indigo launching the missile at least got the idea right.
Matter of perception. To me the effects on Supergirl look better. It's sort of like why one person thinks a comedy show is hilarious and someone else is bored stiff.
And that was just a costume, not really VFX. To me the tornado that Kara had to stop looked just as good as the tornado that Barry had to stop. And the spinning hands effect that Red Tornado used to fly also looked as good as the spinning hands effect that Barry used on the Flash to fly.
She always good for a snappy one liner. And she is sort of a surrogate mother and mentor for Kara, sort of like Joe is a father and mentor for Barry. The show could probably get along without her, but a good drama always has someone for comic relief.
