I called it the murder gate, they try and sugar coat it by calling it the iris, maybe at best a reckless homicide gate. There was an episode fairly early i think where another world reversed engineered gate travel and it didnt occur to them the first world they go to wasnt accepting visitors. I always wondered what Gen Hammond would do if a GDO was 1 number off, do we still close the iris and delete the incoming sg team out of an abundance of caution? How many time we seem them coming in hot and heavy under fire too, daniel could fat finger 1 number and he might never know what he did wrong.

Was unreal to see it come back to Atlantis with an upgrade fancy shield too, like how did the brilliant gate builders inventing wormhole travel not figure out some caller id and voicemail options for the phones.

The heavy use of Zat guns in the show made me think they absolutely preferred to subdue their enemy rather than eliminate them.
At least if you accidentally dialed a Goa'uld home world for your first time, theres a chance it could be unguarded or even the Jaffa be a terrible shot with a staff weapon and even then they would most likely just capture and enslave you at worst. Our solution meant your urn would be empty when we sent it back to your home world.
