There actually is a process of beeing interrupted while working on a plane, which consists of retreat ( you carefully undo the last step you remember doing before beeing interrupted, checking you have all parts in the location they started out, protected against dust etc.). Then you make a note on the step you expected to do. <Interruption> <Return to work> You start out three step before your last step. You repeat/check those steps. Its time intensive as hell, which is why the usual interruption to egostroke for meddle management does rarely happen in aircraft maintenance and production.
