As a plane falls 

The aircraft is the safest mode of transportation there is.

 But something can always go wrong. What are the main risks of flying? And what really can happen during an accident?

Ladies and gentlemen, welcome.

 SincereAir on behalf of the airline who only speaks the truth,

 I ask your attention to some safety instructions.

 First, we would like to congratulate the passengers who are sitting at the bottom of the aircraft -

 in an emergency, your chance of survival will be greater.

 During takeoff, the backrest of your chair should be kept upright. 

This is because, in our new and modern fleet of aircraft, economy class seats are so tight that prevent the evacuation of the aircraft in an emergency.

 In fact, if security were our highest priority, we would put all the seats facing backwards.

Half of the air inside the cabin is recycled, which helps to save fuel. 

This may reduce the oxygen level in your blood, but not usually dangerous - and usually causes a pleasant drowsiness.

 Keep your seat belt fastened throughout the flight 

- or you may be a victim of turbulence, which is harmless to the aircraft, but kills 25 passengers per year.

 Also remember that the seat of your chair is floating.

 Not that it has much importance:

 the probability of surviving a water landing with a large aircraft is minimal ( hitting the water).

 Thank you for choosing SincereAir, and all have a great trip! "
