Islamabad - The planes in the picture have been spotted frequently flying out of Benazir International Airport, Islamabad (BIAI). These are star lifters, heavy lift aircraft of the US army and air force. The question is why are they flying in and out of Islamabad on a regular basis? What are they transporting? Normally these planes are used for large troop movements and heavy equipment lift. When contacted the CAA was unable to respond and the military was unavailable. Is any one keeping a check on what exactly the US is up to in the environs of the Capital and GHQ?
