Yes from Will Rogers World Airport (KOKC) from the long term 5 story parking garage. I work at the airport so when I get some downtime I like to take photos.
Yes. Obviously you didn't answer the door when they attempted to deliver the package. They don't allow you much time from when they knock and then leave as they are on a tight schedule. If it didn't need to be signed for, it would have been left on the porch.
The truck will normally deliver packages to an assigned area. It all depends on how many deliveries are before you on the route. This is why they do not give a specific time of delivery.
