- Images of Turbomeca's Turbo Commander test vehicles equipped with Astafans: [1], [2], [3], [4], [5], [6], [7], [8] & [9]. These images would probably require relicencing to be used on Wikipedia.

- ISAE's 2007 annual report, which notes that ISAE is replacing its Astafan test stand with a more reliable, more modern unit
- Post in Commander-List Digest Archive, describing the history of one Turbo Commander testbed (probably fails WP:RS, unless expertise of poster can be established)
- Aerostar: The Aerostar Log (Fall 2008) 37 (4) reprinting material from Aerostar Log in November 1974 including Ted Smith's speech that includes his experience with the Astafan, and the design decisions related to using it in the Aerostar
