Former member of the Ukraine parliament (Verkhovna Rada) Oleg Tsarev (Oleh Tsariov) told at a radio interview on May 17 2017 that MH17 could impossibly have been shot down by separatists. According Tsarev who now lives in Crimea the aircraft flew at an altitude of 8000 meters.
In 2014 Tsarev was presidential candidate.
Tsarev now calls himself Speaker of the Parliament of republic Novorossia according his Twitter bio.
This is another example of how people with high positions are talking complete bull shit just for propaganda reason.
