Yesterday evening, around 7:40 PM, four F-16s, followed by 4 Marchettis SF-260 carried out a flight over Brussels Cinquantenaire square (Aviation museum).
Right over the square, one Marchetti left the formation for a loop and a "missing man formation", before joining the flight again.
It was a surprise suddenly to hear fast jets at low level, in the evening, with cloudy weather over Brussels. But more here :
