1st recording, there was a problem with Luna’s costumes so Luna, Victoria and Sulli stopped dancing but Amber and Krystal didn’t know it so they kept dancing intensely. Finally Krystal realized it so she went to hug Amber’s neck and shake Amber’s body. So they had to re-record it again

While waiting for Luna to fix her costumes, Amber walked to Victoria and hugged her

When the 1st recording finished, f(x) took a break by sitting at the stage wing. Fans calling their names and Amber responded by raising both of her hands

There was a camera following f(x) during the recording, Amber talked to the camera after 1st recording finished

After 1st recording finished, Sulli and Krystal rested at the stairs beside the stage

When they were about to start the 2nd recording, members walked up the stage. Fans called members names then Krystal turned to them with a calm face as usual lol

After the 2nd recording, it was Luna who talked to BTS camera while Amber and Krystal kept disturbing her

When they were setting their position ready to begin the 3rd recording, fans called out members names and Krystal turned to the audiences and made why-did-you-call-me expression lol

We can see Krystal’s abs very close (3 meters). Her abs are very bright and it was 11 shape, nearly a 6-pack

Luna’s costume was also revealing. If only she wasn’t covered by a net shirt

‘Airplane’ costumes: Amber – male purple basketball shirt, Krystal – female red basketball shirt number 23, Sulli – white-pink one-piece dress, Victoria – Electric Shock style t-shirt, Luna – t-shirt+black shorts

When the fans got into the studio, f(x) already finished their 1st recording and went to check the monitor

Fans there still called out member names, f(4) smile but Krystal remained calm lol

While other members were checking the monitor after the 2nd rec (but 1st rec w/ fans), Amber was stretching

During the break after the 2nd rec, a fan called Sulli and she turned to smile at that fan.SHE WAS SO CUTE!!

About the Airplane choreo, there were prop chairs on the stage. There was one time when Krystal sang her line standing in the middle and Victoria-Luna and Amber-Sulli stood on the chairs. 1st recording, LunToria and SulBer stood there doing nothing but the 2nd time they made the heart shape, so cute!

Before RPPP rec started, Amber raised her hand up to hi-5 w/ Krystal but Krys responded with a fist
