Śrīmad-Bhāgavatam
[ Canto 4, Ch. 12 ]
one likes without mechanical arrangement, so the  ākāśa-patana  airplane can fly at the speed of mind. Beyond this  ākāśa-patana  system is the Vaikuṇṭha process, which is completely spiritual. The airplane sent by Lord Viṣṇu to carry Dhruva Mahārāja to Śiśumāra was a completely spiritual, transcendental airplane. Material scientists can neither see such vehicles nor imagine how they fly in the air. The material scientist has no information about the spiritual sky, although it is mentioned in the  Bhagavad-gītā  ( paras tasmāt tu bhāvo 'nyaḥ ).

TRANSLATION
The great sage Maitreya continued: Mahārāja Dhruva was very dear to the Supreme Personality of Godhead. When he heard the sweet speeches of the Lord's chief associates in the Vaikuṇṭha planet, he immediately took his sacred bath, dressed himself with suitable ornaments, and performed his daily spiritual duties. Thereafter he offered his respectful obeisances to the great sages present there and accepted their blessings.
