R&P would be a good point if the FA instructed folks that they only needed to turn off electronic devices that would impart interference. The instruction to turn off ALL devices doesn't really permit situational evaluation, so in this case I believe the scenario would be closer to breaking a 65mph posted fixed limit.

Agree with you that most facts are true, but sometimes in the statement of a 'fact', dispute may arise in defining the standard upon which the authority of the fact rests. Hence, 'fact' might also indicate an allegation or stipulation of something that may or may not be a 'true fact'.

According to the American Heritage Dictionary of the English Language-4th Edition, "Fact has a long history of usage in the sense 'allegation'". The Oxford English Dictionary dates this use to 1729.

My point in thought was that we can suspend any debate on whether a particular model of phone causes interference. The issue, at least to me, seemed to be a simple case of someone disregarding crew instruction, policy, rules, regulations, etc.

The chosen ones need not be bothered with the rules of which the rest of us peons are forced to comply as they were ordained by birthright to do otherwise.
