Given how many have been retired and/or are unflyable…i bet it was ”more efficient”
Also note – Nolan never claimed it was ”cheaper” to use a real plane
That is an erroneous title given by /u/jervis42:
Though buying a 747 plane and blowing it up may have been more efficient, Christopher Nolan later seems to insinuate that it may not have been the cheaper option
