I e-mailed this to leters@astronomy in response to an editorial in their new March 2015 Issue, entitled "Let's cut the UFO crap".
I worded the letter very conservatively, and did not mention any of the more extraordinary aspects of the phenomenon, such as abduction or contact, physics theories, cospiracy/coverup allegations, etc.
Here it is: Read on and let me know what you think.
============================
David Eicher is correct that that UFO reports and evidence do not establish that UFOs are interstellar in origin. However, a large number of well documented UFO reports fit the description of technology under intelligent control. Scientific analysis of the evidence tells us at least some are physical and have capabilities beyond what our technology can accomplish. The curious and discerning reader can look up literature such as the Sturrock Report, the COMETA report, and other studies establishing the reality of the phenomenon. Then use Occam's razor to draw your own conclusions.
Whatever their origin, unidentified objects in (or from) the sky may well represent one of the biggest mysteries of our time.
