Continuing to examine the past and present air service of the West African coast, the wonderful website Timetable Images offers this schedule of Liberian National Airlines from April 1967, showing services from Robertsfield to Buchanan, Rivercess, Sinoe (presumably landing at Greenville) and Cape Palmas (Harper, Maryland County).
Whats especially interesting is that the service includes a flight between Spriggs-Payne airfield and Robertsfield, a distance of scarcely 50 kilometers, a hop which the schedule allows twenty minutes to complete. A box below details the leg northward to Freetown from both RIA and Spriggs on Wednesdays. A separate matrix details passenger fares and excess luggage charges.
Despite the sleek jetcraft zooming across the glossy cover of the brochure, LNA operated only two sputtering Douglas DC-3s to run its entire network, so recalling this as the golden age of Liberian domestic air travel may be somewhat rose-tinted. According to the Encyclopedia of African Airlines (Ben R. Guttery, 1998), LNA eventually merged with Ducor Air Transport to form Air Liberia in 1974, a carrier which survived until the outbreak of fighting in 1990.
