GTA V Infinite flying glitch
Neat way to fly in the air for a very long time. Go to the very very top of mount chiliad and use the skyfall cheat, it gets so high that sometimes it jams the controls and stops you from turning, and on the odd occasion the textures can disappear and the sky turns black.
You can travel all the way across the map with no issues. I have also seen a floating shark in the air when going over the the ocean but I wasn't recording and haven't been able to see it since.
