Civil aviation authorities in India are struggling to determine what caused at least 10 pilots to report seeing a "ball of fire" in the air on Sunday morning. Described by several pilots as a "ball of fire, orange in colour and scattered," the phenomenon was said to have appeared over the Indian state of Gujarat and has left aircraft officials perplexed at its possible cause. Air Traffic Control authorities in the New Delhi have been asked to investigate the mysterious incident, but initial inquiries found that no aircraft had been reported missing since it occurred. Some in India have already speculated that the fireball could be related to Pakistan's recent short-range missile test. While the neighbouring country had informed all regional aircraft pilots of its intent to test the weapon, it did not offer specifics regarding a testing time. Any future action on the matter would come after the Air Traffic Control files its initial investigative report.
