First, you do realize that's not an aerial map, yes? Quality aerial images for most of the country won't even date too far back, the technology not really being up to snuff until the last 20 years or so, those that do date further back generally lack visibility and detail, the resolution so poor built in zoom features are of little use. Also, a lot of the aerial image sites will often substitute the type of general maps you show in your post for all the above reasons.
