Hey Fayçal, I'll try to explain. This aircraft is a PBY Catalina, it was a very versatile ward bird from WW2. The aircraft on the video is at the Ocaña aerodrome, south east of Madrid. Seems like somebody named this aircraf as "La Mancha witch" and you can see a drawing of Don Quijote and Sancho Panza on the left side. This aerodrome is at 30 min flying from my home airport. It has a long paved runway so is really fun fly to it.
