Took me far too long to work how to get a plane to land, was drawing lines along the runway rather than dropping them on the coloured spot at the end and they were overflying. Was thinking the paths weren't straight enough, once I figured it out was quite funny to find the planes can do 180° turns mid air to land.
Landing either way is not realistic. Even with no wind airports have a designated runway open. For example a straight North and South "runway" has runway 0 and runway 18, and only one will be open at any given time regardless of windspeed.
