That is true about being odd.... Sig does not sell the hatch but does sell the canopy... I just last week received the canopy from them... other distributors world wide have told me that they.... sell the hatch with canopy but only if you buy the fuse... I plan to call sig tomorrow to put this to rest.... not sure of what happen but believe one allen bolt came out in flight and the other bolt broke out of the hatch.... and flutter into a swamp nearby... could not be found.
