The late former President George H.W. Bush used the military acronym CAVU – Ceiling and Visibility Unlimited – in his approach to life.
"In the Navy, we young pilots all prayed for CAVU -- Ceiling and Visibility Unlimited. But, you see, that is where my life is now. Thanks to my family and my friends, my life is CAVU," Bush said on his 80th birthday, according to military.com.
The nation’s 41st president died at the age of 94 Friday at his Houston home. His body will lie in state beginning Monday.
