There are a lot of haters out there right now when it comes to drones and quadcopters which has resulted in politcal figures calling for and ultimately ensuring a registration process. Some the concerns are understandable as people would like their privacy respected. Like any device it is open to abuse by the user, some of which have used them for inapropriate and irresponsible avtivities like flying them over heavily populated areas or recording people without their consent. I get why these people do not like them but the good they can be used for has been drowned out by some of the frezied bad press they have received while other inventions like driverless cars have seemed to be welcomed with open arms.
Practical applications to validate ideas quadcopters can be useful for like building rope bridges on a small scale have already being accomplished. Fire fighters have ultilized them to fly over burning buildings to help them discover any hidden dangers. They also have been an invaluable resource for search and rescue teams as drones allow them to cover hard to reach areas and feed video footage back to their location. The widely covered story of Amazon pursuing the delivery of parcels by drone has also gathered a lot of attention.
The future applications will no doubt be even more widespread and lead to helping both consumers and industry. it is therefore important not to discourage technology companies getting involved in the industry through uncertainty in what restrictive laws may be implemented that would inhibit the market.
Just like any motorized device, It is important for owners to learn how to fly a drone to ensure competence in flight. Flight schools are popping up all around the country to help people become accomplished pilots which should help all parties feel more at ease.
