Military exercises may explain sightings of a mysterious orange light in Central Australia in recent days. The Northern Territory News understands a group of people who live at Ali Curung, an Aboriginal community not far from well-known UFO haunt Wycliffe Well, had seen the strange phenomenon from their front porch at about 4am on Saturday. Several of the group watched as a huge orange ball hovered for an estimated 20 minutes before being chased by what appeared to be four fighter aircraft. Wycliffe Well owner Lou Farkas said some mentioned their UFO experience the next day when they came in for coffee. "They had all just come in on a bus from Alice Springs and none of them had been drinking," he said. "Apparently the light hovered for a while and then three other objects that looked like fighter planes trailed it and were joined by another plane. "Then the orange light just disappeared into nowhere - they thought it was quite unusual, especially with the other lights that appeared to be aircraft joining in." A US military spokeswoman said it was quite possible the stargazers had witnessed a military exercise.
