One of the coolest things in Cliff Rider: All Seasons is the small plane that keeps flying around the mountain. And yes — you can actually jump onto it while riding.
The hardest one is during the Summer season. You need to line up your speed perfectly, wait for the right timing, and hit the jump at the exact moment or you’ll completely miss the plane. 
The easiest method is in the Autumn season on the first level. You can simply launch off the cliff toward the plane, and the timing is much more forgiving.
I’m convinced only about 1% of players will actually manage to land on the plane 
If you think your timing and speed are good enough, go for it 
The moment you finally stick the landing is absolutely worth it
