luckily for you I was just saving some ADS-B records for direction of arrival measurement. The data was collected April 2nd so already very few planes over French airspace. A short sample has just been uploaded to http://jmfriedt.org/adsb_2000kSps2_1uint8_10Msamples.bin in unsigned char complex (interleaved real / imag) as needed by dump1090 for decoding. You can check with dump1090 --ifile adsb_2000kSps2_1uint8_10Msamples.bin that the file is valid. If needed, you can also generate your own ADS-B sentences using https://github.com/lyusupov/ADSB-Out
