Once a person has put some alcohol into their body, their emotions and physical being are already significantly changed. They may still be under the legal limit of intoxication but this does not mean that their faculties are not significantly changed.
There are laws in place that forbid people from operating any kind of heavy machinery after they have been drinking alcohol for obvious reason. It impairs your judgement and increases the risk of injury dramatically.
It is however very common to hear that one individual or the next did not obey this law. More and more people are losing their lives on a daily basis because a driver got behind the wheel drunk and caused an accident along the way.
After concerns of airline pilots flying large commercial planes while under the influence came up, laws similar to driving under the influence were also passed for commercial airline pilots.
As we have all seen, not all the drivers in the world really care about these laws all the time. It is the same problem with our pilots as well, not all of them really take these laws seriously because they feel as though they are above the law. The pilots who fly private planes never have to go under any alcohol tests and thus are more likely to ignore these laws than their counterparts who fly commercial jets.
It is therefore not unheard of that there is a plane in the sky that is being flown miles by a drunken pilot. They do not realize that their vision is impaired and they also cannot coordinate as well as when they are sober so the risk of them crashing the aircraft is much higher than if they were just driving the plane without any distractions. It sounds absolutely crazy, but this kind of stuff actually does happen on occasion.
The passengers in the plane, pilots flying with them or in other planes and even the people on the ground are thus all in danger due to this drunken pilot. Depending on the attitude that the plane may crash from and the size of the aircraft and how much jet fuel it has, the crashes can be extremely fatal.
Should you survive such a crash caused by a drunken pilot, you should seek legal counsel so that you can get compensation for your injuries. There is no way that this should happen under any circumstances.
