Die Holländer haben immer noch kein VFR Nachtflug, deshalb müssen die im Dunkeln IFR fliegen.

Das stimmt nicht, siehe AIP ENR 1.2:

1.2 VFR flights at night (SERA.5005c)
VFR flights outside UDP may be permitted for aeroplanes, helicopters, airships and touring motor gliders under the following conditions (for restrictions see paragraph 3.1):

if leaving the vicinity of an aerodrome, a flight plan shall be submitted in accordance with SERA.4001(b)(6);
flights shall establish and maintain two-way radio communication on the appropriate ATS communication channel, when available;
the VMC visibility minimum flight altitude restrictions as specified in SERA.5005 shall apply. This means that in addition to the daylight VFR restrictions the ceiling should always be at least 1500 FT and the pilot should at all times have the surface in sight. Except when necessary for take-off or landing, a VFR flight outside UDP shall maintain a level at least 300 M (1000 FT) above the highest obstacle located within 8 KM of the estimated position of the aircraft.

Der wohnt (und fliegt) wie ich in den Niederlanden ;-)
