This is definitely taken at Kololo Airstrip after the 25th Jan 71 coup as will be seen by the other photos I have posted. The wings you see are Parachute wings from Maalire Parachute school at Lubiri run by the Israelis (EjW). You can see the pavilion built for the pope in the background of both pictures (EjW).
Joseph Bakibinga (Facebook), “Definitely January 25th 1971. Check out the ‘Sherman tank’ in the background; when Amin toppled Obote while the latter was attending the Commonwealth summit in Singapore. I recall this day vividly as we had just reported to school and a gun wielding soldier came, while we were at the assembly, and ordered the school closed.”
