The summary could be:
This is the second video of a series about the airports of Hong Kong. It tells how the city's economic and political changes in the 20th century created the need for a new airport to replace the old Kai Tak, which had many problems and limitations. It describes the challenges and costs of building the new airport on an artificial island in the open sea, as well as the infrastructure and services it offers. It compares the new airport with the old one and explains how it benefits the city and its trade. It also mentions the plans for expanding the airport in the future.
