Passage: In the second qualifying session, every driver set a lap on the option tyres except two. Lewis Hamilton still managed to take his McLaren into Q3 with the sixth fastest Q2 time on the prime tyres, and Pastor Maldonado, who did not set a timed lap. It was notable that Red Bull Racing and Ferrari needed to use options when Hamilton could use primes. Jaime Alguersuari – a man who had come from far back to score points a few times in , like his teammate did at this weekend set the slowest Q2 time and dropped out on the same row as Rubens Barrichello's Williams. Neither Renault made the top 10, Vitaly Petrov in 12th and Nick Heidfeld in 14th. One Force India and one Sauber failed to make the cut – Kamui Kobayashi (13th) joined Heidfeld on row 7, and similarly Paul di Resta just missed out with 11th.

Passage: Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No. 2 Squadron. Commanded by Major Oswald Watt, No. 2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.
