One of the reasons that the raid was able to be so well planned was that the building in which the hostages were being held was built by an Israeli construction firm. Israeli firms were often involved in building projects in [[Africa]] during the [[1960s]] and [[1970s]]. The firm which built the airport terminal still had the [[blueprint]]s, and supplied them to the government of Israel. But, more importantly, [[Mossad]] (Israel's intelligence service) built an accurate picture of the whereabouts of the hostages, the number of terrorists and the involvement of Ugandan troops from the released hostages di Paris.
While planning the military operation, the Israeli army built a partial replica of the airport building with the help of some Israeli civilians who had helped build the airport terminal. It has been claimed by researchers that after arriving at the military base to begin work on the replica building (not being aware beforehand what they were to do) the civilian Israeli contractors were invited to dinner with the commander of the base. At the dinner, it was indicated to them that, upon completion of the replica, and in the best interest of national security, they would be held guests of the military by remaining a few days. During the entire operation an extremely high level of security was maintained.
According to a [[July 4]], [], Associated Press interview with raid organizer Mookie Betzer, [[Mossad]] operatives extensively interviewed the hostages who had been released. As a result, another source of information was a French-Jewish passenger who had been mistakenly released with the non-Jewish hostages. Betzer reports that the man had military training and "a phenomenal memory", allowing him to give information about the number and arms of the hostage-takers, among other useful details.
In the week prior to the raid, Israel had tried a number of political avenues to obtain the release of the hostages. Many sources indicate that the Israeli [[cabinet]] was prepared to release Palestinian prisoners if a military solution seemed unlikely to succeed. A retired IDF officer, Baruch "Burka" Bar-Lev, had known Idi Amin for many years, and was considered to have a strong personal relationship with him. At the request of the cabinet he spoke with Amin on the phone many times, attempting to obtain the release of the hostages without success.
