Launching and landing is pretty much exactly the same as in a standard pod/stirrup harness. I can't see any issues with aerotowing, though I've not truck towed before so can't say much there — but I don't see why not.
I guess that's the magic here, there is no learning curve required, launch, landing and prone flying is exactly the same. The design is elegant in its simplicity. And it negates the process I went through of spending time/money/energy making bars etc, and launching with fingers tightly crossed. This process led me to the disappointing realization that I couldn't have 100% control authority in a seated position compared to prone. Others say they have full control flying seated, but I can't see it and physics too suggests otherwise. Perhaps full control authority is not a big deal for some, but was for me.
Once you are away from terrain, you can start practicing transitions and seated flying itself. Transitioning is quite quick and easy, but I'd recommend practicing hanging from a tree for a while before heading to launch (and you know the old rule about not introducing more than one new thing at a time). Either way, you want to have it properly adjusted beforehand so that it fits your preferred setup and you are familiar with it's functionality. There should be an instructional setup video released soon, along with one about the finer points of transitioning.
The glider still flies the same, though weightshifting while seated uses a different set of muscles and requires a little practice to commit to muscle memory... it just feels a bit unfamiliar and strange at first. As you would expect. It's a different perspective to see your wing ahead of you flying along, and you hear different noises coming off the wing. It's cool. And of course when flying seated, you don't need to use your hands/arms
It's so nice to be able to boat around so effortlessly and without pain... and when you feel like going fast, just drop into prone and stuff the bar — perfect! This thing ain't like a bog standard PG harness, in that you can adjust angles inflight and end up with a pretty aerodynamic position that is comfortable.
I'm extremely grateful to Bill for his efforts in getting this to market, so that others have an easy and quite economical way to get into seated flying. Oh, and so I can keep on flying safely for another few decades. It's changed everything for me.
