The Biafra's two main airfields were at Enugu and Port Harcourt. Three other landing grounds existed at Calabar, Owerri and Ogoja, but with little (if any) landing facilities, such as landing aids, etc. The loss of Enugu, Biafra Capital in 04 October 1967 and two weeks later Calabar in the South East helped the Federal troops to control the Biafra-Cameroon border and seal off the Biafran coastal ports. We were forced to transfer international communications, including valuable arms flights to Port Harcourt which became Biafra's main outlet to the world till May 1968. Tt was the loss of Enugu which prompted the concept to establishing a series of secret airstrips in the Biafran bush and a team of Biafran engineers
