Not sure what this has to do with millitary aviation
Ah. The same mistake of thinking that 'ground safety' has nothing to do with 'flight safety'.
Given the cost to the MoD (financial, lives, reputation etc), something had to be done. Training and licensing evidently did not work. It appears to be a reasonable idea that was not well implemented. Other similar schemes across many areas (inc Heathrow) have had great success.
