Berlin was always a bit 'iffy' as it clashed with the Berlin Air Show but the question that must be asked is whether Amsterdam is a centre of helicopter excellence?
The organisers did a good job this year but it was they and others who destroyed a certain other upstart Helicopter Show in the UK Midlands with a [hollow?] claim that industry neither wanted nor could afford an annual helicopter show in Europe.
If that claim holds any shred of truth they may be hoisted on their own Petard....
