I've had several local Builder's Merchants deliver 1 tonne bags of sand/top soil etc, and always marveled at the dexterity of the driver/hoist operator. However, I doubt any of them would be able to fly a MAD trap at night. So perhaps a series on Maritime would be of more interest, as well as highlighting the multi-crew aspects of this highly specialised role. Alas, it may be several years before we have the wherewithal to provide the resources to produce such a blockbuster.
