The californian commentators are now talking about Nitrox being dumped
into the capsile for re-entry to keep it cool.
While the technical definition of nitrox includes normall mixture of N2
and O2 in normal atmpsphere, it is generally used only when you have
O2-rich mixture to reduce body absorbtion of N2 while diving (reduced decompression requirements when going back up to surface - and extending
dive time).
Dragon is normally at 14.7 and normal N2/O2 mixture, right? If they use
Nitrox during landing does this mean they are increasing cabin pressure significantly enough to worry aboutr the bends when the bring it back to
1 atm?
Or are the commentators just using "nitrox" to look cool and the cabin maintains normal N2/O2 mixtures?
