I am wondering about how to fully open the alternate emergency exit window. The placard says to “Unlatch - Force forward portion past stop”. I get the need to unlatch the two knobs, but then when the window is open, the forward stop does have any way to disconnect past a stop. Am I supposed to force the window open by trying to break the rivet at the pivot or the connection to the mount? If so, any idea how hard that is? Thanks!
