Have you ever wondered if the airplane is thoroughly checked before taking off every time? Although there is a big list of constraints that are checked every time before a flight takes off, there are still some minor failures that are left unattended to ensure that flights are on time and there's no delay. But don't worry because these minor failures aren't supposed to affect safety provisions. When it comes to in-flight safety, planes are sturdy enough to withstand getting struck by lightning or thunderstorms. It is important to buckle up during flight because most turbulence-related injuries happen when some passengers forget or ignore to fasten their seat belts.
