I don't make air bread, but King Arthur sells a very expensive baking
pan for "sandwich bread". The recipe is on the KA web site
<http://www.kingarthurflour.com>.
Enter "sandwich bread" in the search window of KA's recipe section.
If the pan comes up, there is a link there for the recipe. From the
description and comments by responders, it is similar to the
commercial air bread that kids love. The special pan yields a
near-crustless loaf, according to users, but I think the recipe could
be baked in a traditional loaf pan.
