Note that handling is not compulsory in Bogota airport, but presumably Tyrolean, as a well-respected operator, went through one of the three 'proper' FBOs there. Question is, do outbound, public transport, chartered jets have to go through screening there (as they do in Europe over 10 tonnes), if so, clearly the screening staff were paid off by someone there, or it didn't go through any form of screening at all, legitimately. Colombian police should be all over that FBO/handler like a bad rash. If not, then the airport police are in it, the screening staff in it, etc. etc.
