Windows in airlines passenger cabin is Oval and not Rectangular or Sqaure.

Hi sreejithsreenivas! I think it has something to do about the stress and strain of the plane structure when going against the wind. But I am not really sure how to go about the explanation. I just remember this being discussed in one of my engineering subjects and I can't recall the exact explanation of my professor. Sorry, having a memory lapse on that one! Take care and blessings to you! lovelots..faith
