World Cup airspace defence

Does anyone know what airspace security measures there are for the Soccer World Cup starting tomorrow in South Africa?
The South African Air Force can currently field almost squat to chase and shoot down any highjacked airliners heading for a stadium.
My best info tells me that there are only 4 x JAS39 Gripen D models and 24 x BAE Hawks available for air defence…. and almost no pilots qualified to fly the Gripens.
The Cheetah C was retired 2 years ago.
One 747 plowing into a stadium packed with 80 000 fans would be a bigger disaster than 9/11.
I hope that there are some RAF Tornadob ADVs or French Mirage 2000s helping out, but I worry about where they would be stationed……
The nearest Air Force base to the main events (opening & final) is Waterkloof in Pretoria, and that’s been closed for the last year for the runway to be resurfaced.
The next option is to operate out of the facilities of Denel Aviation at Johanesburgs main airport… but I know for a fact that (as of today) there are no fighters based there.
300km to the north is an ex-air force base (Pietersburg), but that is now a general aviation field and a friend tells me he has seen no military aircraft there in months.
The only operational fighter base is at Makhado (formerly Louis Trichard) and that’s 500km north of Johannesburg…. a bit far for a quick response.
