I notice that they provide a 'restricted distance' of 500 feet for a
pneumatic test of a LH2 vessel tested to 2500 psi. I investigated an
accident involving an LP tank that ruptured at about 60 psi which was
thrown over 200 feet. Someplace there's a report of a nitrogen (GN2)
piping rupture at the Langley research center that pitched 25 or 30 foot
lengths of pipe about the same distance. I think Goddard's chart is
highly optimistic.
