MDA is a man-made (synthetic) recreational drug noted for its stimulant and psychedelic properties that has been used since the 1960s as a clubbing and sex-enhancing substance, with some similarities to LSD and MDMA (ecstasy). Sought after effects.
The soaring temperatures that Las Vegas is experiencing this week could cause grief for pilots at other airports, because heat thins the air and makes it more difficult for aircraft to lift at take-off. To deal with that, pilots need to gain more momentum as they roll down the runway before reaching liftoff speed.
But that is not always possible, depending on the number of passengers on board and the size of the plane. If there is no space, cabin crew are told to cover the person with a blanket up to their neck and tighten their safety belt. If a death occurs shortly after take-off it could result in a plane returning to its airport of departure, while unscheduled landings have occurred in rare cases where a passenger died in-flight.
