    Omg, you are right! That is just the height of arrogance since the only way they could actually provide any protection in the case of a decompression, you know, the thing that is the only job of an extra atmospheric flight suit, would be if there was an air tight sleeve attached to the boots. That would make the pants just fashion and wasted weight being launched. The extra kg of fabric would not add a lot to the fuel costs, but it would be measurable.

    One group of billionaires went squish under the ocean, another is going to end up finding out how they make astronaut food in space.

    I am by no means a material scientist or biologist, but I have studied a lot of them and have some curiosities.

    It would be interesting to see how calcium doping modified the properties of the alloy. AFAIK the temperatures that iron smelts at is to high for the carbonate or phosphate bonds to remain stable, so most of it should have ended up as free calcium or phosphorus.

    I also imagine that the type of bones have a lot to do with it, since avian bones have a different composition and density than say, a moose bone. Different kinds of animals also have evolved different metal doping concentrations.
