European weapons have been used by the Mexican Army and Air Force for a long time, we like them more than the americans, so I think those weapons are going to be around for a while,
This would explain the proclivity for these firearms to end up in the hands of cartels. Contrary to what the hoplophobes and the media (but I repeat myself) will tell you, they're not coming from Uncle Billy's gun store in AZ. They're coming from the 120K or so deserters from the Mexican armed forces and police depts in the last decade or so who often forget to turn their rifles back in when they decide to quit their $300/month jobs to go work for the cartels for ten times as much. The insanity won't stop until the farcical War on (Some) Drugs comes to a close.
Mexico City looks beautiful from 800ft AGL. A huge, expansive city, the modern looking "downtown" area is far more expansive than I would have thought. Looks lovely.
If you're flying around there, how are the safety concerns vis a vis kidnapping, people shooting at your aircraft? I can see why in the north you'd need an armed guard with you as an ex-pat flyer, how about in Mexico City? Looks pretty docile...
