10/31/2007. Remarks by Johan Visschedijk: "This five-seat long-range medium bomber was designed to specification B14/46 and two aircraft were built: VX158, first flown August 10, 1951, and VX161, first flown August 12, 1952. Due to the straight-wing design it laboured under a speed disadvantage compared to swept-wing designes and no production orders were placed.

Both aircraft have been used as high-speed, high-altitude research, and as engine test beds. VX158 was first powered by four 6,000 lb (2,722 kg) st Rolls-Royce Avon RA.2 turbojets, thereafter one 15,000 lb (6,804 kg) de Havilland Gyron Gy1 turbojet replaced the Avon in the lower part of the port engine nacelle. In 1956 it flew with two Avon turbojets combined with two 20,000 lb (9,072 kg) de Havilland Gyron Gy2 turbojets.

VX158 was scrapped at Sydenham in 1957 and VX161 was scrapped at Hatfield in 1958."
