I used to fly in Europe and have had at least 5 practice Dutch intercepts - not a big deal. They are always looking for an excuse to do a practice intercept. They used to come up if asked about 1/3 of the time, and I'm sure had no problem doing an intercept for an airliner on the wrong freq. No big whoop.
On August 10 at around 12:14Z, Delta Airlines flight 073 from Istanbul (IST) to New York (JFK) was intercepted by two Dutch F16 fighter jets over the Netherlands. According to sources, the DAL flight failed to contact Maastricht Eurocontrol UAC.
An MP3 sound file has become available of the interception. It can be downloaded here:
You hear AJ33, which is one of the two F16s scrambled from Twenthe AFB in the Netherlands. AJ33 is talking to Dutch Fighter Control (c/s Bandbox) on UHF, the latter is not audible. The recording is time-compressed; the blanks have been removed from the recording. Later on in the recording you hear AJ33 talking to the DAL crew on VHF guard freq 121.5
