SPANISH drug traffickers are now taking to the skies to avoid border controls.
Smugglers are loading up mini planes with sacks of marijuana in a bid to evade Moroccan security.
Investigations carried out by Moroccan police have exposed dozens of Spaniards believed to be violating their airspace.
Some 13 drug planes have already been intercepted this year, while just seven were seized in 2007.
Last month, two Spaniards were arrested for undertaking a drug smuggling reconnaissance mission.
They were spotted circling over the east of Morocco, in another trademark mini plane.
