Dutch Foreign Minister Tienermann in an interview declared that one of the Australian passengers that died had donned an oxygen masked.
Then he retrieved it as a slip of tongue (like US Vice President Biden when he said that Turkey turned a blind eye to IS…which is the truth, at least initially, as confirmed by the Israeli Mossad in an interview).
You do not have time to wear a mask if a missile hit the plane.
You have time if there was a small bomb, if an air plane was strafing the plane (ops …only Ukrainian had jet fighters).
