Have to point out that the use of the word 'great' is hardly appropriate in this case.
The dictionary defines great to mean 'above average in bulk, number, extent'. 'Above average in intensity'. 'Important, pre-eminent'. 'Imposing'. 'Distinguished'. 'Of remarkable ability' etc.
This clip is none of the above but it does show how a crass decision and ignoring a second opinion cause an accident.
