I'd also imagine a PPL-type person might find the concept of no engine, no go-around quite entertaining...
Definitely. But that's slightly compensated by a 1:30 or 1:40 glide ratio, whereas the types I normally fly sometimes don't even reach 1:10. Oh, and having airbrakes sounds pretty cool to me too.
The other thing is a different undercarriage. No nosewheel but this center-thingy on which you've got to balance the plane sounds interesting too. Fortunately with a glider you don't have these long taxis down a 1500 meter runway.
And I'll probably miss a cockpit filled with electric thingies that show you where you are or shows others who you are, or go beep at various times. And I imagine the checklist in a glider in general is a tad shorter than in a powered plane.
