Here it is significant to note that the yoga-sadhanas of Naropa and Maitripa have detailed knowledge-practices (Tsa-Lung) for clearing all the prana-nadis. Note also that contemporary Tibetan practitioners have mastered both tsa-lung and tummo inner-fire and have demonstrated this empirically in deadly cold conditions which are impossible for ordinary human bodies to tolerate. However, we might also note that not one of them has demonstrated the ability to perform yogic flying (akasha gamana). We might also note that the Tibetans demand this very kind of demonstration every time some yogi says he is enlightened.
The vows and precepts for Lung-Gompas are very strict, so it's highly unlikely you'd ever see this, although novices have been witnessed. If you hold anuttara-level teachings, you can get permission to observe some of the 'hoverers' now in the Himalayas. I have witnessed first hand yogic running, and it is quite odd to see as the person looks like a cartoon figure running up and down hills as if gravity didn't matter.
