Low and Fast,
Your handle suggests that you dont fly twotters
I must admit I am now a bit out of touch with the contract scene, so was not refering to specific operators, but rather the operation of Twotters in unfriendly environments.
In the good old days Rossair had a few, MAF had in Angola, the Marion brothers had at least one in Kinshasa and I recall seein a few in West Africa.
What the present status is, I have no idea?
