1941, Monday 01 December;
The three Bramo 323
Fafnir radial engines, a development of the old Bristol Jupiter, built up power as the flying boat X.32, taxied into clear water. At the controls was Lieutenant Commander Bastiaan ‘Sach’ Sjerp, KM (Koninklijke Marine), commanding officer of Flight GVT 7, taking his Dornier DO-24 out on a long-range reconnaissance flight. This was on the orders of the Dutch High Command, who were working in tandem with the British and Americans, between them putting up an air surveillance umbrella watching for Japanese Naval movements. Their areas of responsibility were well divided, but the areas to be covered were simply huge.
Apart from a general coverage of the Philippines, the Americans took a particular interest over the South China Sea, watching everything northeast of the line Cape Padaran (Indo China), about 35 miles SW of Cam Ranh Bay, to Kudat (Borneo) and onto Sangi Island in the Celebes Sea. The British, who were desperately short on good maritime recon aircraft, would cover the waters as far as Cape Cambodia, and as far south as the Anambas Islands, leaving the Dutch to cover the area south of the Kuantan-Anambas Islands, across to Borneo, and the northern Borneo coastline. The Dutch had agreed this, operating aircraft from Tarakan in the East and
Pontianak in the west of Borneo, but with their other commitments across the entire Dutch East Indies, they were stretched exceedingly thin.
From today onwards, American and British PBY Catalina’s, Australian Hudson Mk II’s, and these Dutch flying boats would be conducting flights with an almost clockwork regularity, weather permitting, and of course the weather was very much a factor in all this, it being the monsoon season for the South China Sea’s. That had to be accounted for, the failed hourly radio report, an aircraft not returning, could very easily be caused by the weather, their loss alone not reason for alarm. The long hours of flying brought fatigue and danger, pilot error on a poor landing, a miscalculated navigation causing the aircraft to run out of fuel. And it tested the quality of an aircraft’s construction, the thoroughness of maintenance checks, of engine overhauls. All this would take a toll.
‘Sach’ was aware of the dangers, but was confident in his plane, and himself. Twenty-seven years old, a pilot with four years’ experience flying these waters, he had been promoted and given command of GVT 7 back in August. His aircraft the Dornier DO-24 was much loved and respected by its aircrew, and although older than the PBY Catalina’s now being bought by the Dutch, was preferred, with the reliability of three engines as opposed to two, and a heavier armament, with a 20mm gun in the dorsal turret.
And then there was his crew, seven of them in total, including himself, which was very green, owing to the expansionist efforts of the MLD (
Marine Luchtvaartdienst), transferring experience crewmen out, and replacing them with newly trained from the schools at Morokrembangan. So, he had an additional pilot, to watch over for a month or so, before the lad would be given his own plane to fly, both his Navigator and Radio Operator had only been with him since back in August, and two of the three mechanic/gunners had joined two months ago, the third, an old hand who knew just about everything about the plane, was their mentor. Despite them being a mix of Dutch, Eurasian and Javanese, they were all volunteers, keen to learn, and got on well, which bode well for the future.
The flying boat gathered sufficient speed to lift clear off the waters, passing the oil jetty’s at Langkas, climbing over Tarakan Island and heading north east, later turning northwest and then again west, following the coastline past the British ports of Sandakan and Kudat, before finally landing in Victoria Harbour, Labuan Island, where there was a small refuelling facility arranged by the British. A similar flight would be done by another DO-24 coming out of Pontianak, Dutch West Borneo. And so, the watch began.
