For all practical purposes the practice session, P1, in Azerbaijan did not happen Friday after a mishap.  The Baku track, being a city circuit like Monaco, has manhole covers that must be secured either by welding or bolting them shut.  Ferrari’s Charles Leclerc hit a loose manhole cover and then William’s George Russell, taking the normal racing line, went over the loose manhole cover and it ripped a hole in the floor board of his car.  Since there are more than 300 manhole covers on the Baku City Circuit, P1 had to be postponed so that all manhole covers could be checked and secured, if necessary.  The drivers missing a Practice session is not a big deal, sessions have been missed in the past due to things like rainouts.  The Williams techs will be putting in long hours to get Russell’s car ready for the Qualifying sessions on Saturday.
