Re: [PSUBS-MAILIST] Discovery channel last night...

[MerlinSub@t-online.de (Carsten Standfuß)]

Hi John - this Trench is 11000 meter (36.000 feet) 
deep - in other words : 

about 11000 x 1,025 = 11275 metric tons per square meter 
pressure - equal to 1047 t per square foot .. 

On the moon the pressure on the wall of your ship will be
below 10 t per square meter (1 bar) equal to 0,92 t per 
square foot - and this is inside pressure - much easier 
for a pressure hull than outside pressure.. 

Maybe the moon seems more save..
