Sadly, the bar, and duration required for the science you describe is higher than "a little research on pubmed...on SARS". I'm a little flummoxed by the description of not rushing science as political.
It's not scientific to assume spread is not airborne, then tell everyone to assume spread is not airborne, until research confirms beyond a reasonable doubt that it's airborne. Science isn't about pretending that the first guess that comes into your head is the truth until proven otherwise.
