Charles, I discovered another safety issue with my legacy latching system. I=
 have a manual lock to keep the handle locked down during flight.  I underst=
and this is to prevent the steps from shaking  the canopy open.  But, if the=
 airplane has an incident and the occupants are unable to release the latch,=
 nobody from outside will be able to use the handle.=20
