Everest's peak is about 29,000 feet above sea level. I imagine this thing flies at, what, 40,000 or so? Why bother pressurizing the cargo hold at all if people can't breathe anyway? You have all the headaches of compression but none of the advantages. Am I missing something?
- margalabargala 1y agoI don't know, but at a random guess, with such immense cargo volume, there could be a danger of implosion during an emergency descent if the hold was unpressurized and the inflow rate was not sufficient. It may have been cheaper to pressurize than have rapid inflow.
- bluGill 1y agothey shouldn't be flying very far, and thus won't even make it to 40k feet before heading down. If you are going more than 500 miles (i made that up but it is a good number to start with) build a new factory. Iowa has kept one factory busy for more than a decade transporting less distance than that.
