Sailors aboard the USS George H.W. Bush sent their ship's namesake a pretty special birthday wish this week.
An aerial photo of the ship was posted on its Facebook page Thursday -- crew members created a "41=90" formation in celebration of the 41st president's 90th birthday.
The former president celebrated his birthday in a big way -- he parachute jumped in coastal Maine Thursday morning.
Spokesman Jim McGrath said Bush likes both a surprise and an adrenaline rush.
"It's vintage George Bush," McGrath said. "It's that passion for life. It's wanting to set a goal, wanting to achieve it. I'm sure part of it is sending a message to others that even in your retirement years you can still find challenges."
The first time Bush jumped from an airplane was when his plane was shot down in World War II over the Pacific. Later, he decided to jump from a plane of his own accord and marked his 75th, 80th and 85th birthdays by skydiving.
He said on his 85th birthday that he'd like to do it again on his 90th.
