Common sense example: A tanker full of fuel falls on it's side. It has a hole now on that lower side which is kept from leaking by the ground. An astronaut is pinned by this tanker. A half dozen engineers are standing around deciding what to do.They roll the tanker 90 degrees and pull out the person; then watch all the fuel pour out of the side until it's gone. Any engineer with an IQ over about 40 would just have turned the tanker yet ANOTHER 90 degrees until the hole was on the top and the fuel stopped pouring out. DUH!

10 ships with about 5 people per ship land on a new planet. They have no clue if there are carnivorous living beings on this planet. Not one single astronaut or NASA engineer thinks to bring weapons onto the trip to Alpha Centauri. Of course a dinosaur attacks them and destroys their stuff. DUH.

An astronaut is severely injured. The MD grabs a full med kit from the vehicle she is in. NASA engineers did not think to pack a MAST (military anti shock trousers); standard fare for any medical pre-hospital care setup. So now all the blood is in the extremities instead of the core and he dies. DUH. Doctor starts compressions. Does about 40 compressions and not one single breath. Not one. Then looks around and just declares "he's dead". Where was that MD trained - Uganda?

Seriously, these writers are idiots. They screw up EVERY single episode. There is no way 50 trained astronauts including Navy Seal Team members are going to have zero common sense and not know what to do in an emergency.
