Didn't Keyhole also own a satellite, which Google would have taken over when the bought the company?
I think you are probably mixing up your Keyholes
The Keyhole that Google bought wrote what became Google Earth.
There were a series of US spy satellites called Keyhole.
I don't believe the two are connected.
Naw, I thought that Keyhole (the company) owned it's own commercial satellite Googling with those terms is painful though, because of the KH-11 and KH-12, though.
