Mercedes mechanics had to use tape as a quick fix for Lewis Hamilton's car after a piece of the floor flew off during Friday morning's pre-season testing session.
The first of the three days went off without a hitch for Mercedes. Team boss Toto Wolff was even speaking very positively about their new car's performance, suggesting it might be good enough to propel Hamilton and George Russell into the title fight this year.
He might have been slightly worried, though, to see a piece of the floor of the W14 fly off during the morning session on day two. Hamilton was behind the wheel at the time, as TV cameras spotted the piece fall off the car and come to rest in the middle of the track.
