Either people ( politicians ) take this issue seriously, with appropriate kit -
or why not use a Cessna Caravan with a 'spotter & his scanner in the back, and a bloke with a good set of bino's ?
I have a horrible feeling which they'd choose !
As others have mentioned, there are some large airframes going secondhand - I can't help thinking this should be instead / would have to be - a buy of new large airframes - C-17 anyone ?
As far as FSTA goes, seems to me they're re-inventing the wheel - slowly, but with 'Euro' stamped on it.
