"This morning we experienced a front wing mounting problem which caused the wing to come off the car at the beginning of a run. The cause has already been identified. Unfortunately, we're missing one or two spare parts which will hopefully arrive this evening, so we won't be able to run for the rest of the day. In the short amount of running that we've achieved so far, we are very encouraged by what we've seen and we have gathered some vital aero data which is very much in the range of what we were predicting. We look forward to resuming the programme tomorrow morning."
