VS, I was under the impression it could be closed again, albeit very difficult to do without 2 or 3 other people helping you... but agree, the 767 door is not that great with regard to the arm/disarm lever. I always did like the drop-out doors, no worry about opening that one by mistake, if you're using it, you're good to blow the slide
Just looking at that Emraer handle has me confused... I've heard the same thing from a number of Virgin Blue crew, they say it's the pits especially when you change from a Boeing mid-trip... and tired... no wonder they keep blowing slides, can't blame them really!
