Cockpit side window of Boeing 737
II hav a small query about Boeing 737, out of curiosity. Could not find a thread on 737, so posting here.
The query is regarding the side windows of the cockpit. Why, in a 737, the side windows have a V-dip on the bottom side? I identify a 737 from a 320 by looking for this V-dip.
And why is this V-dip so sharp? Sharp corners are stress raisers. It could been rounded, maintaining it's purpose.
