Oxygen masks that collapse during an emergency on a flight can only give 12minutes of continuous airflow.

The riskiest phases of a flight are take off and landing.

The longest standing airline in the world is KLM Royal Dutch Airlines which was established in 1919.

The longest flight in the world currently is from Newark to Singapore which takes 18 hours 38 minutes.

Humans lose 40% of bodily water which is about 1.5 litres during long-haul flights of up to 10 hours or more.
