Saturday started with some filter runs in the drill trench, but when drilling was about to resume the drill tower did no longer tilt. This was fixed but drilling was first continued Sunday. This turned out to be THE DAY where we finally managed to have sufficient good weather to have a flight mission to EGRIP. This mission was postphoned from 20 July. 14 EGRIPers left camp and 23 new arrived. Camp population is 31 EGRIPers
