1. The probablility of simultaneous HP hose failures
is vanishingly small. If you carried enough stuff
to cover every vanishingly small failure scenario,
you couldn't swim.

2. HP hose failure is handleable. Modern first
stages have a pinhole oriface behind the HP port,
so the pressure drop is relatively slow. I ran a
test a few years ago. IIRC, the pressure drop was
about 200 PSI/minute. Pressure drop through the
LP port was much higher.

I'll see if I can dig up the test results. They
should be on my home computer somewhere.
