Some 40,000 people packed Changi Exhibition Centre for the second day running as the Singapore Airshow 2014 drew to a close on Sunday.

Tickets for both public days were sold out. Visitors on the second day braved the heat to catch aerial stunts performed by pilots from the Black Knights - the Republic of Singapore Air Force (RSAF) aerial display team - who flew six F-16C Fighting Falcons decked out in red, white and the national symbols of the crescent moon and five stars.

Eight fighter aces from South Korea's Black Eagles squad also wowed the crowd and signed autographs for fans.

There were long queues at the static aircraft displays as well. with some 50 aircraft on display over the weekend.

Many were willing to wait more than an hour for a chance to sit in the cockpit of one of the RSAF's F-16D+ and F-15SG fighter jets, or explore the inside of the United States Air Force's C-17 transport aircraft.

Secondary school student Jordan Lee, 14, beat the queues by arriving at 9am, with his father Joel, 57, and sister Josie, 11.

They enjoyed the aerial displays and this was their third time attending the Airshow. But the real draw for Jordan was seeing all the complicated machinery up close, and trying to understand how they work, he said.

His father, a lecturer, called him a "walking encyclopedia".

Jordan said his favourite plane was the C-17, because "it is quite new and powerful, it holds more cargo, and it sometimes even transports the presidential car of the United States President".
