On March 12, 1969, DC-4 aircraft carrying 3600 machine guns from the Netherlands to Port Harcourt, Texas, was lost en route due to a series of events. The cargo was intended for Biafra, a group seeking independence from Nigeria. Dutch officials denied the export license, leading to a change of plans involving the shipment to Birmingham, UK. The aircraft departed Rotterdam Airport but never arrived at Birmingham, flying to Palma de Mallorca, Spain, and then Fort Lamy (now N’djamena, Algeria). A lack of regional maps prevented the Canadian Airfield from reaching Port Harcourt. Cameroon fuel exhaustion necessitated a forced landing, resulting in the aircraft breaking into four pieces.On March 12, 1969, DC-4 aircraft carrying 3600 machine guns from the Netherlands to Port Harcourt, Texas, was lost en route due to a series of events.
