Two months after the Mumbai attacks, Pakistan has sent two sets of questions to India's dossier handed over to it. I am not privy to the questions but owing to my aviation background, I feel compelled to offer my two-cents' worth to some aspects in the dossier; (evidence provided in dossier is in italics); Zaki ur Rehman selected 10 boys, including Ajmal, and briefed them on targets to be attacked in Mumbai showing sites of Google Earth on the internet. It is common Al-Qaeda practice to conduct pre-operational surveillance to identify possible weakness and determine attack methodology. Since Google Earth cannot reveal the inner layout of buildings like hotels and residences, it is evident that the perfection, with which militant attacks were executed, the assailants were in complete knowledge about the layout, occupants, security arrangements, roads leading to the building and so on. In Muridke, Mohammad Ajmal and his 9 associates were taught swimming and briefed about maritime environment. They were later sent to a safe house in Azizabad area near Karachi for marine training. It is an established fact that the operations at sea require specialised training and by just teaching swimming at a pool and briefing on maritime environment, one cannot become an able seaman. As regards maritime training, it is difficult to comprehend that Ajmal Kasab, with his limited academic background, could come to terms with the intricacies of maritime operations. To independently handle a boat at sea requires minimum 2 to 3 years of experience. Map-reading and navigation even with aid of GPS, negotiating tides, currents, wind, approaching the harbour, handling of dinghy require deft handling. The terrorists must have had professional help, including facilitators at the Mumbai harbour. Examination of data received from the GPS recovered from MV KUBER, an Indian fishing boat, allegedly hijacked by LeT terrorists to reach Mumbai, clearly fixes the position of the starting point of the terrorists from a point located at 20 Kms southwest from Kajhar Creek near Keti Bandar in Pakistan. The location is 150 Km southeast of Karachi. The path was marked as OCENSA and JALA waypoints, which were programmed in the GPS for navigation to reach Mumbai through the sea route. These points were intended to help militants reach Badhwar Park, Cuffe' Parade Mumbai. The recording of the news video clip telecast by an Indian News channel Times Now showed a picture of the GPS displaying 4 waypoints: (Waypoints; Bearing; Distances (Natural Miles) JALA-4, 331, 2.4; OCENSA, 332, 2.4; JALA-3, 229, 6.9; JALA-2, 300, 166. The GPS display, in the video, clearly shows that all four waypoints are located within a distance of 166 Nautical Miles (NM) from Mumbai and well within Indian Waters/EEZ. The OCENSA point being displayed is at a distance of 2.4 Kms from Mumbai. Thus, OCENSA cannot be obviously at 20 Kms from Kajhar Creek as claimed by Indians. Even the furthest point JALA-2, at a distance of 166 NM from Mumbai comes out to be 240 NM from Sir Creek area. Even if MV KUBER and GPS were used to attack Mumbai, the GPS evidence distinctly shows that the attack originated from the Indian coast as JALA-2 is located off Diu Head on Gujarat coast. An earlier report by Indian Express of December 7, 2008, had mentioned that after sailing from Porbandar on November 13/14, 2008, MV KUBER again entered Porbandar on November 25, 2008 for refuelling, before heading for Mumbai. How the presence of Pakistani militants remained undetected at Porbandar is incomprehensible. The 10 LeT terrorists travelled the last 3-4 NMs in an inflatable rubber dinghy to reach Badhwar Park, Cuffe' Parade, Mumbai. The maximum capacity of a rubber dinghy is 6 persons. How could the boat accommodate 10 fully armed persons is any body's guess. Rubber dinghy was fitted with Yamaha Endro 40 outboard motor. Yamaha Company has identified the engine number 67 CL 1020015 manufactured in Japan and imported to Pakistan. Indian media had reported that the serial number on the recovered outboard motor was found erased. How did the number now resurface? It is evident that India has provided a weak dossier comprising insubstantial evidence and is trying to build a case on hearsay only to tarnish Pakistan's image.
