Austrian Soaring Course

WHERE TO LAND?I'm having a devil of time trying to complete this mission.Two questions:1) What time do I have beat to set the course record?2) Where in the heck do I have to land the glider to get credit for completing the mission? After completing the course -clean, and being shown the airport as the next way point, I keep getting a "mission failed","Our telemetry shows that you had an off-landing", whenever I land. I've landed on the runway, grass area of airport, taxi way and even the on the adjacent golf course but always get the same "mission failed" statement .....I'm stumped!Any help or advice would be greatly appreciated.thanx,kenP.S. I've completed 50 of the 51 missions with this freaking glider mission being the last ...All WANT IS THE GREEN CHECK!!!!Heck, I'm not even a glider fan but have spent more time on the P.I.T.A mission than I'd care to admit.
