Departed Lympne Airfield in Kent on 24.4.1924 bound for Rotterdam, Netherlands, and disappeared (probably crashed into the English Channel). Presumed to have been involved in a CFIT (Controlled Flight Into Terrain) when flew into the sea in fog. No wreckage or traces of the aircraft or the three persons on board (pilot and two passengers - named as H. van Hien and C. Modderman) were ever found. Registration H-NABS cancelled 12.5.1924. According to contemporary newspaper reports ("The Gooi and Eemlander" for 25.4.1924, translated into English):

"The distance from Lympne airport to Rotterdam, flown by the French, Belgian and Dutch coast, is approximately 285 km. The cruising speed of the F.III was around 140 km/hr. With the departure of 14.00 ex Lympne an arrival time of 16:00 would have been obvious. But at 17.00 Waalhaven was still awaiting the arrival of H-NABS.

Also, they have not yet received the usual reports from coastal stations Calais, Dunkirk and Ostend. These would relay the aircraft passing, something Captain Pijl could not as the aircraft did not have a radio on board, only a compass.

After it became clear that the machine would not arrive anymore, authorities in the countries along the route were asked to search for the Fokker F.III. Not only aircraft were deployed, including shipping traffic in the Channel were alerted but all in vain. One has to conclude that Pijl nevertheless ended up in the fog over the Channel and may have tried to fly underneath the clouds.

There is not much imagination to think of what that machine, the word "coffin" here is more in place, which occurs mostly triplex (three-ply covering) and the ailerons even from one tissue (fabric). No wonder that of H-NABS nothing was found."
