Space Jockey fused wth the chair

The Space Jockey's Story

The Space Jockey wrapped in his chair

a) Where does biology end and technology begin?

Ridley wondered if the fact it looks a part of its chair was a result of the ossification of the corpse and had transformed that way into something from Giger's mind which was where biology and technology fused together and one could not work out where one might begin and the other might end,  It looked to him as if Giger had grafted the pilot into its seat.

b) Giger's Answer

With Giger's biomechanics style, the Space Jockey turned out to be biomechanical to the extent that it looks as if he has physically grown into his seat or maybe he has grown out the seat, However Giger thought of the entity being totally integrated into the function that he performs and with his seat he forms a single unit.

c) Astronaut sunken into his vehicle and instruments.

Fritz Billitzer in his essay about biomechanoids in Giger's Necronomicon, mentioned as an example of biomechanical relationships in the real world about how an "astronaut is literally sunk into his vehicle and instruments. That he simultaneously studies them while being studied by them",  and i wonder if those words helped form the idea of the space jockey merged with his seat to come along into being.

d) Innocence of the space jockey
Dan O'Bannon always wanted this alien to be an innocent traveler, and was pleased with the final Space Jockey, because in contrast to the alien chestburster that grew into something carnivorous, the Space Jockey did not possess the characteristics of a carnivore and he could imagine it as some totally non violent herbivorous creature sailing around space. Sitting in its doomed space ship, the pilot appeared to be benign and people involved in the film tended to agree, but they couldn't explain why.

1. Ridley Scott: This space jockey is, I've always thought was the driver of the craft who is now after many ages, of course it would be dustless but has started to look like a perfect example of Giger's mind which is 'where does biology end and technology begin?' because he seems to have grafted the creature into what was essentially was let's say a pilot's seat. (alien-20th-anniversary-dvd) 
2. Scanlon & Gross: The space jockey skeleton is, of course, all bones, but it's not so much a skeleton sitting in a chair as a skeleton that has become a part of the chair. It's not clear if the space jockey has ossified with time or was always an organic part of its craft . (Book of Alien)
3. HR Giger : The creature we finally ended up building is biomechanical to the extent that he has physically grown into, or maybe even out of, his seat, - he's integrated totally into the function he performs. (Cinefex 1, p64)  
4. HR Giger : The pilot is conceived as one of my biomechanoids, attached to the seat so as to form a single unit.  (Giger's Alien p34, 25 July, 1978, )   
5.  Brian Muir: I have fond memories of working with Giger. He explained to me and my colleague Peter Voysey that the pilot and cockpit were to be as one, as if merged together. The jockey was modeled in clay, and then cast in clear resin.  (Scifi Now #52 2011, p115) 
6. Fritz Billitzer: Astronaut is literally sunk into his vehicle and instruments. He simultaneously studies them while being studied by them.( Giger's Necronomicon)
7. Dan O'Bannon: imagine it as some totally non violent herbivorous creature sailing around space. (Cinefex 1, p64)
8. Scanlan & Gross: Sitting in repose in its doomed spaceship, the jockey somehow appears to have been a benign creature. People involved in the film tend to agree on this. But they can't explain why. (Book of Alien)
