|PEGASOS-Zeppelin's first scientific flight for 2012|
|Cabin layout number nine, consisting of CPN-, API-, NAS- and NOX-Racks|
The instruments for cabin layout 9 (CL9, nucleation) were already installed (tooled, as the specialists say) on saturday. For sunday, we had a bad weather forecast, so we had the chance for some free time (which most experimentalists still used for working on the instruments)

For today, the weather forecast was looking good, so we moved the airship out of the hangar at 10:30 a.m. After the pre-flight checks were done by the pilot, it was realized that switching the electricity for the racks from generator ground power to airship power did not work as expected. The troubleshooting turned out to be complex. After a few hours of hard work, the engineers and technicians of Zeppelin Luftschifftechnik managed to find and fix the problem.

As a consequence of that, we were able to start the first test flight at 3:30 p.m. After 3/4 of an hour, the scientific staff on board was changed and another 15 min flight was performed. All instruments on board seemed to perform well and quick-look data from the flight was later on discussed.
