I landed at Lower Loon Creek Airport and it doesn't give me the reward. I have tried reversing on the runway and it still doen't give me the reward. Please help me!!Thanks

It should as long as you land near the runway and come to a stop near the runway. If you land outside of the area defined for the landing then roll into the area it may not register and if you land and while still going too fast roll out of the area it may not trigger.
