Have you ever looked at the cockpit of a Boeing 737, 707 or 727 and wondered why there are a couple of "spare" windows above the regular cockpit windows?
In this video I will tell you all about why those windows were fitted in the first place and why they seem to be disappearing from newer variants of the Boeing family.
I hope you will enjoy this video and all the others in my Boeing 737 series.
