Why is it only drones that are a threat as Cyborg said I used to fly RC fixed wings and heli's for fun and these granted were harder to fly out of the box but were so much faster and had real fuel in them so were already explosive!
If all we need to is a swarm of drones that are battery operated with a limit on range then our Navy and Army are screwed! This would would mean there is no need for the huge budgets to purchase high tech aircraft when they could just buy a load of drones and weaponize them themselves, Just think if these drones are so dangerous why are we still sending ground troops in we could just send in some drones and save on lives and ammo!
There seems to be far too much hysteria around drones and the threats!
If a Mavic or Phantom or Inspire can fly for say 30 mins (if not returning!) then the distance it can travel given windage is ok on a calm day but factor in some bad weather or rain and his theory is rubbish!
No need for long range ballistic missiles just get a local team to fly some drones at major infrastructure and bomb them, this will be how wars are fought in the future, consumer drones with C4 payloads!
Not sure where I can get C4 from in the UK our local supermarkets dont sell ammunition so I might have to wait until the 5th of November and just get some fireworks!
