Would like to read the next page. You really left me hanging at "Another interesting point is that the...."!

What this seems to say is that the safety factor over limit load was 20%. Limit load is the maximum allowed load. If your design is supposed to maneuver to 6Gs then that is limit load. 7.2Gs would include the 20% safety factor. The safety factor used in most current designs is 50% so I'm surprised at the low design value.

Interesting that the Aussie example had better results than the UK example. That could be chalked up to variation in the testing apparatus however.

I am at the museum on Wednesday and will get you the 16th page bdk. But it usually means the butler did it in detective books.
