Production Observations

I have spotted one production Link between Alien and Prometheus, also one other "industrial" observation, Alien - Prometheus Link: In Alien, when Dallas is in the air ducts on his fateful hunt, take a look at the sides of the duct. You will notice steel embossed plates wth holes in their corners. These are, in fact, plate heat exchanger plates. They are used to give the industrial look to the Nostromo's ducts. I know about PHE because I used to make gaskets for them. Now, lets move on to Prometheus and the scene of carnage after the Juggernaut has crashed and come to rest. As our heroine, Shaw, walks to find the lifeboat you see in the foreground a PHE plate! Now, did the Prometheus set design crew know this or did they have access to previously used Alien paraphenalia? Industrial Observation: In Prometheus, during the Fifield fight scene: when the vehicle is being reveresed to "squish" Fifield, the tyres of the vehcle are clearly marked "Trelleborg". This is the name of one of the largest tractor tyre manufacturers in the world and is a real company! It is the only real world company I think I can remember in the whole film. I am not sure if any one will find these observations interesting but for me they add a little more to our knowledge about the film.
