This is the last part of a international long distance flight from Copenhagen to Tokyo (Narita). Landing at Narita Airport at the end. (Better analysis will follow..)
This recording is made by detektor in a international flight from Copenhagen to Tokyo somewhere above Siberia in near of Mongolia. The signal is comparatively quiet: A lot of Rhythmical and repeating signals.
Detektor flew again to sky above 10000m up. Here how the BTS Signal fades out after 15min, when the place takes off and after some time (18:00), all GSM phones, which are still in operation/switched on try to reconnect after some time. Around 29:36 you can hear a GPS signal.
The detektors was recording during a standard flight from Berlin to London. You can hear that the permanently existing high pitched tone (base transceiver station (BTS) signal of mobile phone network) dissappears between 32:30 and 33:35. This should also be the time of takeoff of the plane. Afterwards you can hear clearly the famous rhythm of a GSM phone, 3G mobile phones and other signals. People don’t repect the instructions of the plane crew to switch off all electronic devices. Does somebody know what kind of signal at i.e 47:00 was sended? Also at 120:00 interesting sounds are hearable! This must have some connection to the airplanes communication with a control tower. Aroud 126:00 the high pitched tone which dominates the infoscape of a urban city gets hearable.
