Yeah, I similarly have dowels floating around my desk for tying hitches. But I don't have a good solution for practicing knots that are meant to be tied under tension, like the "trucker's hitch" family. I've been considering getting some small dock cleats and screwing them to my desk.

> a great stopper knot (Oysterman’s Stopper Knot)

Also known as the Ashley stopper knot! I've started keeping a short length of paracord on my desk to practice knots during video calls. It makes a great fidget toy. The Ashley stopper is what I've been tying this week and it's such a gem (but a little harder to untie than I'd like).

ABOK is the classic. But I was surprised to learn recently that it's not the final word on knots. Superior knots like the Zeppelin bend don't appear in it and there have even been useful knots invented since it was published. Geoffrey Budworth's "The Ultimate Encyclopedia of Knots and Ropework" includes knots that were invented in the 80s.

Thank you, that's really helpful context. I can easily imagine that failure mode playing out. The last thing we need is for it to become some kind of culture war.

Maybe local pressure would be more appropriate once the FAA approves G100UL for all engines. Then it could be about encouraging airports to make sure G100UL is actually available, and getting airlines like Cape Air to switch over their fleets.

That's very helpful. Thanks for explaining! It looks like the Lycoming O-540 engines on Cape Air's new Tecnam Travellers aren't on the list either.

I'm glad you think that G100UL should work in the Cessna engines and it's "just" a bureaucratic issue. Do you have any sense of what the current blocker to approval is? I found Paul Bertorelli's AVweb article a bit hard to follow.

Is it worth trying to apply pressure at the local level? I read that Santa Clara County banned 100LL in January.

I have young kids. We live near Hanscom Field and spend a lot of time near Barnstable Airport. Should we try writing our local airports/cities/counties?

At Barnstable Airport, the big operator is Cape Air. They make a big show of being green, so maybe they'd want to be early adopters of G100UL. Does anyone know if the existing G100UL STC applies to Cape Air's fleet? Could they switch to it if they wanted to?
