Fantastically detailed Boeing 777 model made from manila folders

Luca Iaconi-Stewart is building a "1:60 model of an Air India Boeing 777-300ER made entirely from manila file folders," with an unbelievable level of detail (it even has working mechanisms!)

Though Iaconi-Stewart has photo-documented the project in great depth and provided many notes on his progress, I can't find any explanation about the fundamental questions raised by this (amazing!) project: why manila folders? Why Air India? Why a 777?

According to a Jan 2014 Seattle Times piece, he started work on this in high school, five years ago, and wants to do some design work when he's done.
