Jeff Leser has announced his forthcoming book (publication date to be advised)on the Italian airborne forces 1936-43. I have helped him a tiny bit with his research, and based on the thoroughness displayed by him in these interactions this should be the final word on the subject.

The fact that it is published by one of the most rigorous publishers in the field, Helion & Company, further strengthens my conviction in this regard.

Keep some spare change handy.
