Leadsled I was in Chino last year when they had the worst ever mass shooting in Vegas.
Capn Bloggs, I asked a very well known flying instructor over there, "But how can he do that?"
The answer is simple, you have been given traffic in front of you to follow, and when it is clear for you to land, you can land....simple. His work as a Class D ATC was complete.
Worked the very same way when I flew into Oakland in San Francisco in a VFR Duchess. No Radar to the ground, no flight plan, no notice. The only trouble we had was getting the controller to get our callsign right. Our thick Aussie Accent means that Echo sounds like every other letter except Echo!
