What astronauts and/or pilots had their "own" T-38 for transportation and practice? It appears that the T-38 was used as a means of transportation for certain personnel. Astronauts, and certain pilots? It appears it was also used for training in some cases.
From some articles regarding astronaut training, it seems that some of them had their &quot;own&quot; T-38, that they could more or less use arbitrarily for transportation and training.
I'm curious what pilots and/or astronauts had access to T-38's, and to what degree they had their &quot;own&quot; plane. What were the limitations surrounding their use? Could an astronaut of the Apollo era, take the T-38 for a recreational trip to some other airport?
I'm thinking of articles such as this:

Yes, the jets were used for transportation to training sites.

and this

After the announcement pilots could fly the F-117 during daytime and no longer needed to be associated with the A-7, flying the T-38 supersonic trainer for travel and training instead.
No pilot or astronaut has &quot;their own aircraft&quot;. Not in any unit I've ever seen.
Their name might be painted on the side of one, but they fly whatever the maintenance shop gives them for that day and mission.
Transportation? Sure. &quot;Major Snuffy has to go to Houston for some training on the FooBar hardware. Ralph, take him, and go back on Thursday to pick him up.&quot;
Of course, this counts towards flight hours, mission and route planning, etc, etc.
&quot;Borrow&quot; a jet&quot;? When I was stationed at Griffiss AFB NY in the late 70's, we sometimes had a pilot go for a weekend cross country. Leave Thursday or Friday afternoon, come back Sunday afternoon. Off to Frostbite Falls, MN Regional airport, to visit Mummy and Daddy for a couple of days. And we were loading golf clubs, skis, whatever, in the underwing travel pod.
