The members of the British Airways engineering team must be masters of their trade in all aspects of the mechanics of a working aircraft, and with this mastery comes the need to be very handy with the tools of the trade. This is an open-ended question that allows you to talk about what you feel is the most important tool in your work. As you prepare for this question, make sure that your answer directly relates to the duties you will be performing in this role and, if possible, try to point out a unique skill that you have with the tool that you decide to talk about. This will help potentially distinguish you from other mechanics who are interviewing for the British Airways team.
