The Paper Air Challenge (PAC) is a long-standing competition held every semester at ESEIAAT. The event originated in 2013 and, since then, has established itself as a highlight within the university community. Despite being primarily aimed at aerospace degree students, anyone willing to participate is welcome!

The contest consists of designing and building an aircraft using mainly paper, cardboard, and few additional materials that, according to the established regulations, is capable of flying the maximum distance possible.
