Nick,
I would not throw stones, if I were you. The cert on the S-92 says it uses 30 minute contingency power to hover and it can not take-off or land above 3500' HD. It would be really embarrassing to loose an enemy sub (or whale) because you had to break off after 31 minutes.
I hear you are bringing a S-92 through the DFW area soon. I hope it is a cool day, or do you plan to truck it in like HAI?
