peterson of course is the reference of choice.

does the canopy react pressure ? (don't think so)

does it react flight loads ? (don't think so)

difficult to see what fatigue calc (or any stress calc) you can do.

MeImran,

Could you post your document as a .pdf or other neutral format? I'm one of probably many people who avoid opening Word ".doc"'s from unknown sources.
