The History of drones
The earliest drone appeared in 1839, when austrain soldiers attacked
the city of venice with unmanned balloons filled with explosives.
Some of these Austrian balloons were successful, but a number of them blew
back and bombed the Austrian's own lines.
However, after several failed prototype launches, the british military
chose to scrap the project, believing that unmanned aerial vehicles had
limited military potential. A year later an American alternative was
created called the Hewitt-Sperry Automatic Airplane.
The modern history of commercial drones began in early 2006 government
agencies started utilizing it disaster relief, border surveillance
and wildfire fighting, while corporations began using drones to inspect
pipelines and spray pesticides on farms.

from the earliest forms of aviation such as kites and attempts
at tower jumping to supersonic and hypersonic flight
by powered heavier than air jets. Kite Flying.
The wright brothers invented and flew the first airplane in 1903,
recognized as "the first sustained and controlled heavier than air powered

when he set forth the concept of the modern airplane.

Airbus A380
The Airbus A380 is a double deck wide body four engine jet airliner
manufactured by Airbus. It is the world's largest passenger airliner, and the
airports which it operates have upgraded facilities to accomodate it.
The A380 made its first commercial flight on October 25 of 2007 with
Singapore Airlines.
As of 2016 the list price for an A380 is $432.6 million dollars but there
are negotiated discounts for big corporations and airlines. Thats just the
main cost but what builds up is the operational costs, according to AirInsight
its estimated that it costs $26,000 an hour to operate due to its high end
technologies.
