The destruction of the McKay-Carter bridge prompts proposals for an iris or another physical barrier at Midway. Authentication, an interrupted gate chain and a vacuum transit area are alternative security measures, though the necessary signalling capability is uncertain. Restricting transit to puddle jumpers would still leave a threat from Wraith darts, which can pass through gates. At Stargate Command, protecting Walter behind a blast shield depends on warning that the link has been compromised. The exposed glass control-room wall is criticised, while another contribution points out that the show's original camera technology was more limited than today's.

Defending Stargate's Midway link
Physical barriers and protected control facilities could preserve the Midway transport link while making an intrusion easier to contain.
