Drones (A True Book: Engineering Wonders)

Originally developed in the early 20th century for military purposes, unmanned aircraft, or drones, have come to be used for a variety of purposes.
Readers (Grades 3-5) will find out how drones work and what it takes to pilot them. They will also learn why the use of drones has become a controversial issue, how unmanned aircraft have been improved over time, and what today's engineering innovators are planning for the future of drone technology.

Dezvoltat initial la inceputul secolului al XX-lea in scopuri militare, avioanele fara pilot sau dronele au ajuns sa fie utilizate pentru o varietate de scopuri. Cititorii (clasele 3-5) vor afla cum functioneaza dronele si ce este nevoie pentru a le pilota. De asemenea, vor afla de ce utilizarea dronelor a devenit o problema controversata, modul in care avioanele fara pilot au fost imbunatatite de-a lungul timpului si ce planifica inovatorii de inginerie de astazi pentru viitorul tehnologiei dronelor.
