Srimad Bhagavatam Canto 08, Chapter 11, Text 12

SB 8.11.12

praharat kulisam tasma
 amogham para-mardanah
sayano nyapatad bhumau
 chinna-paksa ivacalah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
When Indra, the defeater of enemies, released his infallible thunderbolt scepter at Bali Maharaja with a desire to kill him, Bali Maharaja indeed fell to the ground with his airplane, like a mountain with its wings cut off.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
In many descriptions in Vedic literature it is found that mountains also fly in the sky with wings. When such mountains are dead, they fall to the ground, where they stay as very large dead bodies.
