In May aviation enthusiasts spotted something odd: giant four-engine A380s taking off on flights from Seoul South Korea and heading nowhere.
Performing 20 minute loops over the Yellow Sea the superjumbos took off from Seoul Incheon Airport to return back where they came from. Seventeen similar flights were recorded by Traveller.com.au over a period of two days.
Any sighting was enough to excite plane spotters, with most of the 500+ passenger jets sitting idle due to travel restrictions. However, these flights were exceptionally odd, not only because they were 'flights to nowhere' but – according to flight manifests – they were completely empty of cargo or passengers.
The special mission these planes were up to? Keeping pilots in practice.
The planes belonging to Asiana Airlines were performing a standard aviation procedure, due to the lack of viable routes the carrier had to arrange "practice flights" for commercial pilots.
To keep A380 pilots up to standard they need to prove proficiency behind the controls every 90 days. This can normally be done on the ground in the cockpit of a training simulator. The closest A380 simulator is located in Thailand. However because not even pilots are able to travel as much as they used to, the airline had no other option but to arrange these 'practice' flights in the world's largest passengers planes.
