Currently in its "first" pre-delivery test flight is another SWISS CSeries, a CS300, manufacturer serial number (MSN) 55029.
It left the ground at 10:23 (14:23 UTC) from CSeries assembly facility located at Mirabel airport YMX/CYMX close Montreal.
SWISS will be taking its next CSeries within the next 48 hours, another CS300 MSN 55023. Look for it leaving Mirabel airport direct flight to Switzerland.
