As a regular visitor to pprune this is the first time I've become aware that the search engine does not accept 3 letter words - and as far as I'm aware the first site that I've come across that is limited in this way ! This is precisely when I've had problems e.g. recent initial search for 'DHL' even though following a wider search I found a current thread in Freight Dogs & Cargo ! When this thread was running back in April I was incommunicado in Florida for a couple of weeks and didn't get to see it then ! I normally do set all the defaults for maximum search potential !
"As potential professional pilots, you are expected to be intelligent and resourceful, and use initiative, lateral thinking and logic in your efforts to become a pilot. If pprune Search defeats you, what hope for the rest of your career?" ………ouch !!
