Lol, drag indeed. Find any conveyance with successive transverse solid ribs. With portholes in-between, so your skyview remains pristine, unsullied by other passengers? Luggage racks, visual confirmation of your tags and destination? Or if reclining and tired of cabin so devoid of glass panels?

Alright, that's enough. As a vehicle though, plenty of unadvertised features.
