Answer 1

Cinturón cohete

Denominado originalmente en inglés como Rocket belt, rocket pack o jet pack u otros nombres similares, son diversos aparatos, usualmente colocados en la espalda, que usan motores de propulsión a chorro cuyos gases al escapar permiten volar al usuario. El concepto evolucionó desde 1920 cuando Buck Rogers, -héroe de ciencia ficción- usó uno de ellos para viajar.

Jet pack, rocket belt, rocket pack, and similar names, are various types of device, usually worn on the back, that use jets of escaping gases (or in some cases liquid water) to allow a single user to fly.

The concept of these devices emerged from science fiction in the 1920s and popularised in the 1960s as the technology became a reality. Currently, the only practical use of the jet pack has been extra-vehicular activity for astronauts.
