De Kooy, late sixties

[BennoT6]

Hi,

I have seen some pictures; of an "Open House" at De Kooy which obviously took place in the late sixties. Must have been 1966, 1967, 1968 or 1969. Someone having a date for an Open House in these days? Even better, who has a list of the aircraft & helicopters which took part, in the flying-program and/or static?

Thanks in advance.

Regards,

Benno
