Really? I thought the seat would always have to force its way up betwwen the two halves of the canopy as the LCC only cut the perspex, it didn't move it out of the way or shatter it as with the MDC'd rear.(E shaped LCC cut in the air Vs D shape on the ground using the emergency canopy shattering handle thingy No matter how long the "knives" though, I wouldn't have fancied barging my way through that thickness of plastic if the LCC failed. Maybe thats why everyone used to stuff so much stuff in their kneeboards!!
