The Asteroid
23 January 2017 | by Claudio CarvalhoSee all my reviews

When a civilian finds a large asteroid en route to collide on Earth, the SG-1 concludes that life will be destroyed with the impact. The SGC tries unsuccessfully to contact the Tok'ra and the Asgardian seeking for help. Sam suggests to repair the Goa'uld ship that crashed in Ravenna and use a naquadah bomb to change the route of the asteroid. When they are ready to explode the asteroid, they make a discovery that will change their decision.

'Fail Safe" is a tense episode of "Stargate SG-1" with Sam trying to find a means to save Earth. The description of Daniel about the dialog of Jack with the Asgardian is hilarious. My vote is eight.
