Hogwash ? It is simple physics. When the drone is transiting through the window the downward thrust is no longer constant and equal, some of the thrust is pushing against the ground, some against the sil, some against the inside floor. Go fly a drone through a window 10 times. You wish crash at least 5.
Going through a doorway, is fine, a window which by definition is going to have different elevations present is a horrible idea.
Yes Hogwash.
