How did the survivors feel the moment they left the fuselage ?

A moment that stuck with me in the movie is when the survivors are leaving by helicopter, and suddenly the music stop when the door shuts and you see Fito trying to keep the fuselage in sight as he fly away.

I’m very sensitive to change and nostalgia and I wondered if any of the survivors talked about their feelings during that moment. To think about how they were building up their new society during 2 months, and in the blink of and eye they're leaving this place in which no one else but them went through such remarkable pain, hardships and camaraderie. Can’t imagine that bittersweet feeling when they realized that it’s over while being pulled away so quick from their friends and family who died in the mountains.

Surely that must have been hard, have they publicly talked about what they felt in that moment ? That would be interesting to hear
