You won't lose a wing when flying through turbulence
, and the media and entertainment industry generally massively over exaggerate the extent to which turbulence can be a problem. In fact turbulence is not much a problem, and pilot just prefer to avoid flying through it in order to make the journey more enjoyable and comfortable for customers.
Turbulence is not the danger you think it is, and that risk has been hugely overhyped by the media, television and film industry which is consistently wrong about turbulence. In fact turbulence is not such a great danger. A wing will not fall off and the engine will not stop working due to the strange turbulence. The plane will simply continue flying and will not be severely disturbed by turbulence. It will not crash. Flights from New York to La Romana or flights from London to Zagrebencounter turbulence very frequently but do not fear that turbulence will make the plane crash.
Turbulence, simply crossing from one air current into another is not inherently dangerous in and of itself. But the effect of turbulence can cause problems when two planes are travelling close to one another. Air craft controllers like it when airplanes stay on course so that they can safely predict where an aircraft with be directed to. Turbulence becomes a problem when there the planes are caused to have their trajectory or altitude altered. But generally normal flights from Manchester to Vancouverare sufficiently able to withstand normal turbulence that will be encountered. But usually when there is a significant storm planes will go a long way around it and only encounter a little of tempest that they meet.
So while the plane will not get ripped apart there is still a chance that passenger could be injured so you should always buckle your seatbelt.
