Probably made by the same guy that made the circular runway project ( same NLR bureau)
Why have windows at all on an aircraft when other visual means exist and are used daily.
I was told long ago that it was also for crew to see which side in in flames before opening doors and emergency exits on pax planes. you do not need one in very seat put at certain intervals.
Out of a curiosity, can you transport legally pax in a cargo aircraft (one with no windows at all )
