West Africa radar coverage
No, I am asking how come there are so many flights that do manage to get through with narcotics in their cargo - undetected. Is it simply due to local corrupt officials and lax customs controls, or is it really possible to fly in undetected? These flights originate in Venezuela (SVBC, SVMC, SVMG) and Brazil. I can't imagine they are flying VFR without filing a flight plan with local authorities, so if they do file an IFR flight plan, why is it that they manage to land, ostensibly refuel, and take off again for even doggier locations like Kidal or Gao in Northern Mali? And large planes can land on makeshift dirt landing strips in the desert. It has been done before.
