             "It also came to light during the investigations that the detainee did not possess the relevant qualifications to pilot the aircraft, and that the helicopter’s airworthiness certificate had expired at the time of the incident." 

The former Cuban military helicopter pilot passed himself off as an instructor ok but he shouldnt have a homicide charge for the lack of a VFR flight plan from a backyard, AWC expiration the subsequent engine failure. The killed passenger was the owner of the little death trap after all. I guess Spain is like America is now, guilty by association or guilty until proven innocent.
