An amusing story about the 'rock festival' that was held when they opened that 'taalmonument':
There was significant air force involvement. Three Sabres flew high overhead to leave '100' in smoke trails; a 16-ship Harvard formation in '1', '0' and '0' line-abreast sub-formations flew past; a Harvard 'spotter' to make calls to this formation to keep its shape (also acting as a 'spare' if any of the others dropped out) flew below and nearby; the Silver Falcons flew low overhead giving a display leaving orange, white and blue smoke trails; an air force officer was on the ground at the taalmonument to call for these runs to start to fit in with timings at the 'rock festival' below. There was a lot of r/t talk and for about 20 mins it was continuous. Every single word on the r/t was in English!!
