Tourist,
The data that PDR1 posted demonstrated that it would be difficult to hold a laser beam onto an aircraft at a few thousand feet, at least for long enough to affect the pilot/s.
But however difficult it may be to 'hit' an aircraft the fact is that some users have been able to achieve this, as demonstrated by the many reports to CAA and other authorities.
There are clearly many of these lasers in the wrong hands, and a 'success' rate of 1% or even 0.1% in hitting an aircraft is still too much.
Where Gouli and PDR1 have gone too far is to suggest that their calculations prove the pilots' reports and actions to be false or with some ulterior motive. That is offensive and unacceptable.
