Romain Grosjean believes he was on course for a place in the top 10 shoot-out before his dramatic crash in Q1.
The Frenchman has got particularly friendly with the barriers this season and his latest off came at Turn 5 as his unstable Haas went out of control, effectively knocking out himself, Lance Stroll, Pierre Gasly, Marcus Ericsson and Pascal Wehrlein from the session.
Grosjean made the lonely walk back to the garage after a quick medical check and rued a costly crash for more than one reason.
"The car felt really good in the first run," Grosjean said back in the paddock. "I was sure we could go in the top ten.
"I went out for a second run and the car went on the nose, so we need to understand what happen.
"I was just trying to catch it in Turn 4 but went on the grass and ended up in the wall on the other side.
"Massive oversteer, for some reason.
"I need to understand why it was so good on the first run but lost it on the second.
"It was a shame because I could have qualified in the top ten."
