Cliff,
Oxygen has to be made in a large plant and can not be produced in the field. Actually it can now (medical home breathing units for instance, but they are not high pressure to fill tanks) but they did not have that technology widely available then. Aircraft breathing oxygen tanks would have been topped up from banks of cylinders filled at the factory. Those 4 tanks would not have enough in them to fill more than a squadron of planes. Lang
