Felipe Massa remains perplexed about how his heavy Monaco Grand Prix practice crash unfolded, despite agreeing with Ferrari that it was not a technical problem.
The Brazilian slammed into the barriers at Sainte Devote in final practice.
"When I braked over the bump the car touched the floor and I locked both front wheels," Massa said.
"It's not an easy thing to happen, normally you only lock one.
"And then I went into the wall - waiting for it to arrive was not a nice thing.
"I looked at the data, and honestly, when I braked I was in a gear lower than I was on Thursday. I locked both front tyres and it was very strange that it happened."
Ferrari made a huge effort to repair Massa's car but it ran out of time to get him out in Q1, leaving him 22nd on the grid.
"It is the worst track to have such a problem," Massa admitted, "but I think we need to remain positive and we will have to try everything we can for tomorrow.
"Monaco is difficult to overtake at, we know, but anything can happen."
He confirmed that he had not been injured in the incident.
"I feel a few pains in the muscles in my back, but I'm OK and it's nothing that a massage won't sort out," Massa said.
