Question Mark (aircraft) Question Mark (aircraft) Question Mark (""?"") was a modified Atlantic-Fokker C-2A transport airplane of the United States Army Air Corps. In 1929, commanded by Major Carl A. Spaatz, it was flown for a flight endurance record as part of an experiment with aerial refueling. "Question Mark" established new world records in aviation for sustained flight (heavier-than-air), refueled flight, sustained flight (lighter-than-air), and distance between January 1 and January 7, 1929, in a non-stop flight of more than 150 hours near Los Angeles, California. Following the record-setting demonstration, the C-2A was returned to transport duties. In 1931 more powerful engines replaced
Parking Non-Stop recordings, with many of the percussion sounds on "Species Corridor" being derived from recordings of slate captured in their local derelict quarries. This attempt to capture the sound of their local environment results in what the group have called a "rural industrial" sound. The three members had previously worked together with Welsh singer Rheinallt H Rowlands and hints of Evans' orchestral arrangements for that artist are also at times evident in Parking Non-Stop. They have been compared by various commentators to artists such as Stereolab, Einstürzende Neubauten, Kraftwerk, Broadcast, Throbbing Gristle, The KLF, Matthew Herbert and Tatu.
