Class Ziemke, together with Bastian Bätz, started work on the code which would later become the Flight Software Framework in late 2009 as a student at the Institut für Raumfahrtsysteme at Universität Stuttgart.
Besides Bastian Bätz and Ulrich Mohr, who were the main developers for Flying Laptop's Onboard Software, the following PhD Students contributed to the project:
"A dream would come true if the software framework I developed would be released in the public domain so that it can be used by other projects and to be used for teaching students how to program on-board software in the course of the studies at the IRS"
- Claas in his Diploma Thesis
Rouven Witt, who developed the FDIR concept and kept morale high as the team's Spaßbeauftragter.
Marek Dittmar, who started work on the ACS code and later tried to keep the development in time.
Nico Bucher, who performed software tests and as such was invaluable during the development.
