Noah

Noah was crazy until the rainfall
and then he was a sage.
The ark preserved from flood waters
and he took center stage.
The Wrights were batty until the flight-test
and then they were astute.
The aircraft changed travel worldwide
and they snatched the salute.
Salk was loopy until the vaccine
and then he was a czar.
The polio virus was blocked
and he got the five-star.
Glenn was wacky until the orbit
and then he was a cause.
The space program advanced all life
and he bowed to applause.
Ford was nutty until production
and then he was a brain.
The assembly line made cars cheap
and he won the campaign.
