I saw a TV report that the possible cause, that made the plane crash in the recent tragedy in Buffalo- New York , is the formation of ice on its wing (or fuselage) . How is this happening and is the quantity of the forming ice so big that it causes the fall of the plane?

Some of these answers are getting ridiculous (and yet they still get thumbs-ups). The primary threat of ice buildup as far as stall is concerned is that it disrupts the smooth flow of air over a wing causing the sudden loss of lift. People need to stop talking about the weight of the ice, as that’s like complaining about the weight of the tiger standing on you while he gnaws on your throat.

Christopher H has it backwards: lift is generated by the shape of a wing because air travels faster over the top of the wing. The higher velocity over the wing results in a lower pressure, and lift is basically the suction over the top of the wing. It is essential that the amount of turbulence in the flow over the wing be controlled: a little bit of turbulence in the boundary layer helps it stick to the wing longer, but if you get into large scale turbulent flow, it becomes separated from the top of the wing. This fully turbulent flow swirls chaotically over the wing and the low pressure distribution that created the suction (lift) is just gone.

A CNN reporter said the plane would roll toward the side where the ice was "heavier," but that’s not what causes the roll. This "tripping up" of flow is kind of a fuzzy process, and it is not likely to occur at the exact same time on both wings. One wing will then probably stall first and the plane will roll toward that side since the wing isn’t lifting anymore.

Im going to Las vegas this week and Im scared ever since 9/11 that the plane might crash, explode, or be a terrorist on board. I never been scared before that but now I am. So whats the % chance of it crashing?

Everyone will tell you that it is very rare and they’re right. Tens of thousands of flights take off worldwide every day, but how often do you hear about a crash?

Let me put a number on it for you. The Boeing 737 600-900 series, one of the most widely used aircraft in the world, has a hull loss rate of .07 per 1 million departures. A hull loss is an accident in which the aircraft cannot be repaired.

The most dangerous part of the trip really is the drive to the airport. Relax and enjoy the flight. If it really was dangerous, the pilot wouldn’t get on board.

Email stated: Airbus $200,000,000. TITANIC? This new Airbus 340-600, the largest passenger airplane ever built, sits just outside its hangar in Toulouse , France without a single hour of airtime.

Enter the Arab flight crew of Abu Dhabi Aircraft Technologies (ADAT) to conduct pre-delivery tests on the ground, such as engine run-ups prior to delivery to Etihad Airways in Abu Dhabi .. The ADAT crew taxied the A340-600 to the run-up area.

Then they took all Four engines to takeoff power with a virtually empty aircraft. Not having Read the run-up manuals, they had no clue just how light an empty A340-600 Really is.

The takeoff warning horn was blaring away in the cockpit because they had All 4 engines at full power. The aircraft computers thought they were trying to take off, but it had not been configured properly (flaps/slats, etc..)

Then one of the ADAT crew decided to pull the circuit breaker on the Ground Proximity Sensor to silence the alarm. This fools the aircraft into thinking it is in the air.

The computers automatically released all the Brakes and set the aircraft rocketing forward. The ADAT crew had no idea that this is a safety feature so that pilots can’t land with the brakes on.

Not one member of the seven-man crew was smart enough to throttle back the engines from their max power setting, so the $200 million brand-new Aircraft crashed into a blast barrier, totaling it.

The extent of injuries to the crew is unknown due to the news blackout in the major media in France and elsewhere.

This is a bit weird but i was thinking about that air france crash today n i was wondering what do you think people felt like before it crashed do you reckon they knew what was going on? I just don’t know how to comprehend what people would feel like i know its best not to think about it though:S

The way I look at it is- with sudden loss of Cabin pressure above 10,000ft you have less then 30 seconds before unconsciousness in a stress-full situation- It causes a fatal condition called Hypoxia – lack of oxygen to the brain. As most flights are flying above FL25 (above 25,000 ft) you aren’t going to notice much at all. Even with oxygen bags dropping should you happen to get it on within that 30 seconds, If the aircraft is losing altitude as drastic height in a crash situation the fuselage will be very unstable shaking and most likely throwing air bags out of reach, The Negative G force you will feel will leave you in able to make conscious thought anyhow as your blood will rush to your head causing grey or black out. (Hence why NASA pilots are subject to strenuous forces and pressure suits before they are allowed to lift off for acclimatisation).

To me, this is a comfort that anybody in a serious plane crash would have known little about what was happening as they ‘fell from the sky’. As a passenger Jet is so heavy and travelling at such speed it falls at an incredible rate anyhow at thousands of feet per minute. Should anyone be unlucky enough to not suffer from the conditions above- they wouldn’t know about it for long anyway.
Terrible situation and my heart is out to everyone on the Air France flight. Rest in Peace.

For example if the window is missing or there is a small hole while the plane is in the air, will it cause people to be sucked out the window or the plane to crash? Please backup your answers with sources, I seen this on Mythbusters once but I can’t find any solid proof!

small hole or window, usually is not enough to bring down aircraft. unrestrained people can be sucked out, if the hole is big enough.

a Hawaiian based airline had a plane thet lost a huge section of the fuselage, it landed OK. it was about 10 years ago.

this is a pic of the aloha airlines plane,

So I’m going on a holiday for a month and I’m taking the JAL airline (Japanese airline) I’m leaving in about 2 more days & just thinking about flying scares me really bad. What are the chances for an airplane to crash and is there anyway that I can do to just keep my mind off of it? Thanks.

Considering the number of planes taking off and landing in the world at any given time, air travel is relatively safe. Sure, NO ONE can say that you won’t crash, but… NO ONE can also say that you will not get hit by a car next time you cross the street.
Many people are scared of having a plane crash but how many are scared of getting hit by a drunk driver the next time they are on the road?

I can not tell you HOW NOT to be scared, but, keep rational and think in terms of there are more death on the road each weekend that there are more death from plane crashing..

Hope this helps.
Cheers from Australia
(I fly domestically and internationally regularly for over ten years now)

Between the years 2001 – 2006, the US airline industry experienced the safest period in aviation history with only one major crash. However, since then crashes and fatalities have risen, making an aviation accident attorney mush more important. With an average of sixty-one thousand people in the air at any given moment over the United States, crashes and accidents are a given. Though they do not occur often (it has been a long understood fact that an airplane is the safest way to travel), when they do occur they can involve hundreds of individuals, several insurance companies, and dozens of regulatory agencies. Thus, a specialized attorney has come to the forefront to help the families of those injured or killed get restitution for their losses.

Aviation attorneys not only hold law degrees, but often have commercial piloting experience or advanced degrees in aeronautical engineering. They need this diverse experience to help sift through the vast amounts of data available when a commercial airliner crashes. Their ultimate goal is to figure out why the plane crashed. The causes for a plane crash can vary greatly. These causes can include pilot error, maintenance issues, the age of the plane, runway issues, weather conditions, improper weight distribution of people and cargo, or terrorist activities. Under some of these conditions there is no accessible liability. Crashes caused by weather conditions or terrorist activities are usually not considered to be under the control of anybody. However, all the other conditions require of some assessment of liability.

To assess this liability an aviation accident attorney must discover exactly why an airplane crashed. This can be a difficult process. Depending on the size of the aircraft and the manner of the accident one or several local, state, and national regulatory agencies may be involved. A successful lawyer must know how to work within these sometimes conflicting agencies. On top of governmental aspect, there are also powerful insurance agencies working on behalf of the airline company. These insurances companies, while not denying obvious fault, will try to construe the evidence of fault in the airline’s best interest. Thus, because of this, private individuals hire lawyers to fight in their best interest.

Aviation accidents, of course, are not limited to large commercial crashes. The number of people flying in personal or private jets continues to increase. With so many planes in the air, crashes and accidents are likely if not commonplace. These small scale accidents, while not nearly as complicated as the larger commercial accidents, still require specialized attorneys to assign legal blame. When dealing with accidents involving small private planes, insurance companies like to blame in the inexperience of the pilots. However, an aviation attorney can be to light such details as safety of the aircraft design, maintenance history, and the pilot’s aviation history. Thus, an increase in these specialized lawyers is increasing even in the private realm.

Incidences involving cargo planes also require legal guidance. These accidents offer different challenges than other incidences. These differences are mainly attributed to the amount of cargo on a plane. Accidents can be caused by pilot error, the age of the airplane, or the uneven distribution of weight associated with the cargo. It is the responsibility of the lawyer to decide which, if any, of these instances occurred. Therefore, for all the reasons listed above, an aviation accident attorney can become important should you need this type of specialized representation.
