Looks like Warren has it all wrong again !
Anyone who knows about such things wouldn't make such a stupid statement.
If you could extract all the gases from within the Hindenburg and still
maintain it's volume then it would float much better than with hydrogen
filling it.
Learn some basic physics and then you would not make such stupid statements.
What matters is the OVERALL volume and the OVERALL mass. Divide mass by
volume and you get the density. If this density is less than that of the
air is resides in then it floats ( rises) otherwise it sinks.
For those like Warren that don't understand, the mass of a vacuum is ZERO.
