On February 20, 2015 Bombardier Aerospace announced that the CS300 jet has received a flight test permit from Transport Canada (TC). With the flight test permit, Bombardier plans to start CS300 flight testing this week. The first flight of the Bombardier CS300 is planned to be on one of the days from February 26th to the 28th, 2015. Bombardier will announce the exact day around 48 hours prior to the event. Bombardier announced on February 24th, 2015 that the first flight will take place on the 26th, however it was canceled for the 26th due to weather. Update: The first flight has taken place on February 27th, 2015. The aircraft took off at around 11:02 AM EST. It looked like the CSeries CS300 first flight was to be televised live on Bombardier's CSeries website, however the company chose not to have a live broadcast.
