Race to First Flight

In early June the aviation world still wondered which aircraft would fly first: the Bombardier CSeries CS100 or the A350-900. Then, in the week before the Paris Air Show Airbus managed to get the A350 up in the air. During the Air Show Bombardier officials still stated that the CS100 would fly until the end of June, aka in the last week of June. Then First Flight was delayed until "by the end of July", due to an upgrade of the software. The end of July came and Bombardier once again delayed the first flight, now only saying that it would happen "in the coming weeks".
During that time Low Speed Taxi tests happened and Transport Canada recently awarded the Flight Test Permit.
During the Moscow Air Show two airlines announced that they would take five CS300 each from Ilyushin Finance Lease (VIM and UTAir Ukraine).
But we are still waiting for first flight and we haven't heard of any high speed taxi test and the RTO (rejected take off). And now we hear that Boeing is not too far away from getting the B787-9 in the air. So which aircraft will be first to get the landing gear up from the ground? Once again the (virtual) race is on. Of course none of the two manufacturer will rush just to be first - safety is always first! But it's time for Bombardier to prove that the CSeries is not a paper aircraft!
