A little on the tiny side, but marked with yellow dots, here are the three jets together in one frame.

Here is a photo of a single jet, that my buddy Kelly told me is likely to be a Dassault/Dornier Alpha Jet made in the EU.

Here's another of the jets which are described as 'light attack jets' or trainers.
Since I viewed these over Scottsdale, Arizona, I'd guess they are in the training mode.
