Queen's Day in the Dutch Caribbean, 1964. The carrier Karel Doorman was in port for maintenance and its S-2A Trackers from VSQ 4 were flying from Hato for a couple of weeks. 169, 166, and 146 are seen here. The fourth aircraft, 189, belongs to Curaçao-based VSQ 1 and is a Canadian-built CS-2A, lacking the characeristic ECM dome above the cockpit. Photo by: Hans Mol / Jaap de Moo r collection
