There was a bug that carried out the mission in the railjack cockpit.

They're responding to hostile NPCs with turrets during a railjack mission to capture the Corpus sisters.

It's time to get right into the fleet, and on the way out, you can't see the warframe like a screenshot above, and you can only see the cockpit.

I was forced to carry out the mission without knowing how to do it, and I wonder if this was the case for other people.
