OOps, had the wrong natural disaster, it was a flood, quoted here by the Intl Commanche Society:
Plans were in the works to do away with the Comanche and Twin Comanche well before Hurricane Agnes flooded the Susquehanna River and inundated the Lock Haven plant in June 1972. Piper said that production of any more Comanches and Twin Comanches wouldn't be feasible, because the tooling and dies for the Comanche and Twin Comanche were destroyed in the flood.
Did all of my multi training in a TC. What a wonderful plane.
