Most sore throats result from viral infections, usually colds, but possibly influenza. In children or adults who were not immunized, the measles, chickenpox or whooping cough can cause a sore throat. Sometimes, a canker sore or fever blister forms in the throat, causing intense pain upon swallowing.
Many vehicles available today come with fuel pump shut-off switches. These devices are essentially circuit breakers that sit inside you car's airbag control module's inertia switch, which is supposed to trigger when the vehicle comes to a sudden stop.
Most airplanes flight manuals require fuel pumps off after engine shutdown and on only before departure. Usually they don`t explain why they should be off for refuelling. I remember reading somewhere that having the fuel system pressurized will increase refuelling time, but I don`t remember where I read that!
