Sorry, as a long term lurker and only occasional SLF, 'i know nuffink about nuffink' when it comes to aviation.
But I like to think that I can recognise a proper day's work being done. The folks in the two CL-215s, three CL-415s and the AirCrane (if I'm right) that we saw near Kalamaki on Sat/Sun certainly seemed to fit that bill.
To go from contact with one less than predictable and hazardous element to drop it on another, repeatedly and over a long period...well I was certainly impressed.
