BAKU, Azerbaijan -- Since joining the Formula One calendar Azerbaijan Grand Prix has forged a reputation for being wild and unpredictable. This year's event has been no exception and we haven't even reached the race yet.
To recap, here's what's happened so far:
On Friday, a loose drain cover shredded through the underside of George Russell's Williams car in the early moments of opening practice when he drove over it at high speed. The English driver predicted it had been 10-15 millimetres from breaching the cockpit.
That session was immediately cancelled so safety checks could be carried out on the rest of the 6km circuit, which features more than 300 drain hole covers.
