Why did the head of Google lead an effort to recover sunken rocket engines?

The two huge engines, originally part of a mammoth Saturn rocket, were salvaged from the bottom of the ocean to be restored for later display. Though a team led by Amazon CEO Jeff Bezos fished the engines out off Cape Canaveral, Fla., the engines are still the property of NASA. The engines fell in the ocean after the rockets separated as a regular part of one of the moon launches during the 1960s and 1970s. Bezos’ space company, Blue Origins, has a NASA contract to develop a private space taxi to the International Space Station.
