It has been going since before YouTube was created. I remember downloading the .MOV files from their web site back in 2003. PetWORKs is the company/creative group behind the project.
Yes, the Moewe/Open Sky project has been going on since 1995. There was an RC model, a large glider, and then this full-sized one with a jet engine. This one first flew around 2013, but now they have more control, can get more altitude, and can fly around the pattern.
Sadly, it needs too much runway to land at summer comiket.
