The dutch preliminary report did end some of the controversial theories that went around:
1. The claim that Ukraine ATC deliberately had MH-17 descend to FL330. The report states that Ukraine ATC wanted MH-17 to climb to FL350, but that the MH-17 crew reported that they were unable to comply.
2. The claim that there CVR/FDR was tampered with: The report found no eveidence of tampering.
3. The claim that Ukraine ATC deliberately changed the route of MH-17. MH-17 requested the reroute themselves, not on initiative of Ukraine ATC.
4. The 'gun-down' theory is now even more unlikely, as both FDR/CVR ended their recording at the same time without indication of trouble. This means that both systems were damaged simultaneously, a very unlikely event in case of canon fire, but fitting the case of a missile hit.
5. The claim that the holes were both entry as well as exit holes: the holes were caused by high speed objects entering the plane from the outside.
Probably some other theories went bust that were both too bizar and too unimportant to remember.
Despite the earlier DSB claim they could carry out the investigation in their offices using satelite images and using the internet, I sense a strong urgency to go to the crash site and do some field work. With the present cease-fire, what are they waiting for?
The most interesting news came from the chairman of the Dutch safety board. He explained to the press that metal fragments (using the word 'sharpnel' would imply missile parts) were recovered from the bodies of the pilots and these fragments were now being investigated wether these are parts of the airplanes or something else.
Last week, a Belgian dentists working on the identification process also explained that every body/bodypart is scanned for metal fragments as part of the identification process.
