So why not give anyone who claims clairvoyant extrasensory perception (also known as remote viewing) a chance to test their ability? ESP, it has been widely noted, seems to work best when there is an emotional connection with the target. A missing airliner with 239 occupants meets that criterion far better than a pack of Zener cards with uninteresting symbols.
When (if) the mystery is solved, the clairvoyant perceptions could be graded on an accuracy scale from "completely wrong" to "correct in every detail." With a large enough sample, a statistically significant data analysis could be calculated.
Almost surely most responses from clairvoyants would fall somewhere outside the two extremes. But it would be fascinating to see exactly where on the scale. Responses could also be broken down by the alleged percipients' demographics, if such information were sought at the time of the experiment -- according, for instance, to sex, location, age, nationality, &c.
If all responses were solicited via email, the time and date stamp would add another variable.
This is not meant to treat lightly what will very likely turn out to be a tragic event. Nor am I suggesting that the results of the experiment (which would take a while to analyze) determine anything about the search strategy, which presumably is being carried out according to standard operating procedures based on experience. But it couldn't hurt to try, if a group of scientists would open their minds enough to conduct the procedure.
