Good point, BUT during my last flight I checked my  bars at several altitudes.  We weren't very high when I lost bars - somewhere around 10,000ft.  So your statement has merit, but is not enough to disprove my suspicions.  You really don't have any more proof than I do.  That just leaves it up to personal judgement.  So there it is.  I have read all your posts, and none of them show me that conspiracy theories are out.  There is just to much evidence otherwise.
