The 1989 Portuguese Grand Prix will forever be remembered for Nigel Mansell getting black flagged, having a collision with Ayrton Senna, then being banned for the following race. Sam Smith and Andrew van de Burgt join Glenn Freeman to discuss that huge controversy in great detail, as well as everything else that was going on in F1 around that time, including tension between Alain Prost and McLaren-Honda, Williams bringing a new car out so late in the season, Onyx firing one of its drivers and getting a memorable underdog podium, plus the only lap in F1 that was ever led by a Minardi.ASK US ANYTHING: Get your questions in for our series finale using #BringBackV10s on Twitter or email bringbackv10s@the-race.com
