The new passenger terminal at Seletar Airport is designed for 700,000 passenger movements a year – up to four times the estimated maximum capacity of the current airport. The two-story, 9,500-sqm terminal on the eastern side of Seletar Airport is expected to be completed by end-2018
Postcards from Seletar 
Good to see the old place being used again. Did my National Service there from 1950-1952. Played every piano on camp.
