Jet powered aircraft have a number of advantages over conventional internal combustion propeller driven aircraft.
To start with, jet engines can operate in a much wider range of conditions. Propellers lose their effectiveness at high altitudes and at high speeds while jet engines are capable of operating at much higher altitudes and a much much higher speeds with little or no loss of power.
Jet engines have fewer moving parts than internal combustion engines which makes them easier and simpler to design, build, maintain and repair.
Jet engines run on fuel that is very similar to diesel fuel, and is much safer to handle and store than gasoline.
Jet engines can produce much more thrust power for their weight than conventional reciprocating engines do.
Turbo driven engines have more high-speed moving parts and so can be prone to wear and tear more than superchargers.
The structure of the airship is based on a metal alloy frame. Lift is provided by multiple internal balloons or cells filled with gas that is lighter than air (hydrogen or helium). Forward motion is driven by propeller engines. Steering is accomplished by means of fins.
Propeller engine, also called turboprop, is a members of the jet family. Each aircraft has a unique mission and therefore a unique propulsion requirement. Transport plane carries cargo a long distance, but it does not have the high speed requirement. So transport plane use propeller.
Are diesel engines better than gas engines is sort of a yes and no question. Diesel engines generally get better fuel mileage and last longer overall. But, gas engines are easier to maintain on your own and gasoline is much more readily available than diesel fuel is on the whole.
Yes they are still being used but they are not popular. That answer is true for military airplanes but for civilian airplanes propeller driven airplanes are the MOST flown and more of them are being manufactured than jet planes.
Reverse pitch propellers allow the propeller blades to rotates to an angle that produced thrust in the opposite direction direction of flight. This allows propeller driven aircraft to stop faster than they would with braking alone.
absolutely they are better. if they are rebuilt right that is.
Diesel engines normally get better fuel economy than gasoline engines.
Slow cars driven fast are always more fun than fast cars driven slow. Squealing tires, engines bouncing off limiters, dabs of oppo and elbows.
It could for emergencies, or for passing other vehicles on the road. It may also be based on the dynamics of gasoline driven engines.

A pull propeller is more efficient due to the fact it is in clean/non turbulent air.
