Summary
Zero Day was in a high pressure deadline when the original vfx staff came to realize they'd need to outsource sequences to meet the Fajr Film Festival timing requirement.
So Reza Misaghi (Zero Day VFX Supervisor) offered our team at Bluejay Production House to work on airplane interior scenes, which we took as appreciation.

I was solely responsible for 3d tracking over 20 shots of the airplane interior scenes in a week time so they could get in the composite stage as soon as possible.
Hopefully the production crew were absolute professionals, and the whole footages were supervised fair enough to reduce the technical challenges as much as possible. I had to go overdue for a couple days to get a clean and reliable result though. But I guess the final movie came out to be worth the hard work everyone has put through.
