Just back from Leeuwarden and everything is visible from outside (even readable).
- The north side (6x F-16 PolAF, 6x Typhoon RAF & 6x EF-2000 GAF) can easily be seen from the 'spotters hill'.
From the same spot also the 8 Swedish JAS-39s are visible (parked tarmac South 3).
N 53 12 59.6, E 5 44 12.9 (spotters hill)
- From the southern crash gate the 6 Finnish Hornets are visible between the buildings (parked tarmac South 2)
N 53 13 3.4, E 5 45 11.1 (crash gate, Poptawei)
- Finally, the 10 Norwegian F-16s (and Finnish Hornets and a few Swedish Gripens) can be seen from the main road (parked tarmac south 1).
(in parking order: 659, 289, 291, 670, 667, 681, 295, 663, 277 and 299)
N 53 13 10.6, E 5 43 45.6 (main road Bitgumerdijk).
Not satisfied yet, from N 53 12 52.7, E 5 45 38.7 7 Norwegian F-16s can be seen between the buildings/hangars (only 6 aircraft are readable from here, being 670, 667, 681, 295, 277 and 299).
No BAF or RNLAF F-16s spotted (all parked in shelters).
Good luck!
