Looking back 2015 in ANWS, I would like to express my thankfulness on the devotion of our colleagues who have insisted on their responsibilities of flight safety commitment. They have been providing aviation services 24 hours a day in all year long. They are truly the guardians of the sky. I thank all our staff for their hard work, dedication and remarkable performance during the past year under the circumstances of increasing traffic, climate change, and even shortage in
manpower.
