하늘에 나타난 저 이상한 빛은 무엇일까? 이 독특한 빛은 밝을 뿐 아니라 움직이면서 퍼져나갔다. 평소와 다를 바 없던 캘리포니아의 샌 프란시스코에 위치한 금문교의 밤하늘 위로 천체사진가와 그의 친구 앞에 이 모습이 나타났다. 그들 뿐 아니라 최소한 백명 이상의 캘리포니아 주민들은 이 이상한 장면을 목격했다. 그들이 하늘에서 목격한 것은 사실 로켓 발사로 인한 불꽃으로, 트라이덴트 II D5 핵 미사일을 잠수함에서 발사 시험을 비공개로 진행했던 것으로 확인되었다. 이런 실험들은 일반적이지는 않지만 많은 사람들이 대부분 모르게 대도시 주변에서 해진 직후 가끔씩 진행된다. 불꽃의 사진들은 곧 바로 인터넷에 게시되지는 않았지만, 바로 알려졌고, 하늘에서 이런 신기한 장면을 목격한 사람들은 정확하지는 않지만 훨씬 거창한 설명을 덧붙이곤 했다.

Explanation: What is that unusual light in the sky? A common question, this particular light was not only bright but moving and expanding. It appeared just as the astrophotographer and his friend were photographing the Golden Gate Bridge in San Francisco, California against a more predictable night sky. They were not alone in seeing this unusual display — at least hundreds of people in California reported a similar sight. The consensus of experienced sky observers was that the plume resulted from a rocket launch — an explanation that was soon confirmed as an unpublicized test of a submarine-launched, unarmed, Trident II D5 nuclear missile. Such tests are not uncommon but do not usually occur just after sunset near a major metropolitan area — when they are particularly noticeable to many people. Were plume images not posted to the Internet and quickly identified, such a sky spectacle might have been understood by some to be associated with more grandiose — but incorrect — explanations.
