'Houston, we've had a problem'
These nutrients flood into the bloodstream, supplying energy to all parts of the body. All of these changes happen so quickly that people aren't aware of them. In fact, the wiring is so efficient that the amygdala and hypothalamus start this cascade even before the brain's visual centers have had a chance to fully process what is happening. That's why people are able to jump out of the path of an oncoming car even before they think about what they are doing.
As the initial surge of epinephrine subsides, the hypothalamus activates the second component of the stress response system — known as the HPA axis. This network consists of the hypothalamus, the pituitary gland, and the adrenal glands. The HPA axis relies on a series of hormonal signals to keep the sympathetic nervous system — the "gas pedal" — pressed down. If the brain continues to perceive something as dangerous, the hypothalamus releases corticotropin-releasing hormone CRH , which travels to the pituitary gland, triggering the release of adrenocorticotropic hormone ACTH.
This hormone travels to the adrenal glands, prompting them to release cortisol. The body thus stays revved up and on high alert. When the threat passes, cortisol levels fall. The parasympathetic nervous system — the "brake" — then dampens the stress response. Many people are unable to find a way to put the brakes on stress. Chronic low-level stress keeps the HPA axis activated, much like a motor that is idling too high for too long. After a while, this has an effect on the body that contributes to the health problems associated with chronic stress.
Persistent epinephrine surges can damage blood vessels and arteries, increasing blood pressure and raising risk of heart attacks or strokes. Elevated cortisol levels create physiological changes that help to replenish the body's energy stores that are depleted during the stress response. But they inadvertently contribute to the buildup of fat tissue and to weight gain.
For example, cortisol increases appetite, so that people will want to eat more to obtain extra energy. It also increases storage of unused nutrients as fat. Relaxation response. Herbert Benson, director emeritus of the Benson-Henry Institute for Mind Body Medicine at Massachusetts General Hospital, has devoted much of his career to learning how people can counter the stress response by using a combination of approaches that elicit the relaxation response. These include deep abdominal breathing, focus on a soothing word such as peace or calm , visualization of tranquil scenes, repetitive prayer, yoga, and tai chi.
Most of the research using objective measures to evaluate how effective the relaxation response is at countering chronic stress have been conducted in people with hypertension and other forms of heart disease.

Those results suggest the technique may be worth trying — although for most people it is not a cure-all. For example, researchers at Massachusetts General Hospital conducted a double-blind, randomized controlled trial of patients with hypertension, ages 55 and older, in which half were assigned to relaxation response training and the other half to a control group that received information about blood pressure control. After eight weeks, 34 of the people who practiced the relaxation response — a little more than half — had achieved a systolic blood pressure reduction of more than 5 mm Hg, and were therefore eligible for the next phase of the study, in which they could reduce levels of blood pressure medication they were taking.
Physical activity. People can use exercise to stifle the buildup of stress in several ways.

Exercise, such as taking a brisk walk shortly after feeling stressed, not only deepens breathing but also helps relieve muscle tension. Movement therapies such as yoga, tai chi, and qi gong combine fluid movements with deep breathing and mental focus, all of which can induce calm. Social support. Confidants, friends, acquaintances, co-workers, relatives, spouses, and companions all provide a life-enhancing social net — and may increase longevity. It's not clear why, but the buffering theory holds that people who enjoy close relationships with family and friends receive emotional support that indirectly helps to sustain them at times of chronic stress and crisis.

The forces acting on them - lift, weight, thrust and drag - tend to balance each other out, meaning the plane will fly straight and level unless the pilot does something to alter that. For instance, if the pilot increases power, the aircraft will climb; but eventually the speed will reduce, meaning lift will reduce, meaning the plane will level off.
Even if the pilot let go of the controls altogether, the plane would eventually reach this straight-and-level equilibrium. There are limits beyond which the plane won't correct itself automatically, for instance, if it flies too slowly or climbs too steeply it will stall meaning the wing no longer generates lift.

A stall is perfectly recoverable, and are only deliberately created in testing new aircraft and training new pilots so they can recognise the symptoms and learn how to react. All modern airliners have automatic systems which either alert the pilots to these situations well in advance or stop them from happening altogether. It might also help nervous flyers to understand what happens before and during a typical flight. All of these procedures are standard and extensively understood and practised by all pilots.
A lot of work goes into ensuring that flights are safe well before aircraft take off, and the aviation industry has a strong safety culture. The routes taken by commercial flights are typically planned by experts who seek to ensure that the flight is as safe and smooth as is possible. Pilots can amend these routes before take-off and during the flight to further improve the comfort and safety of their passengers. The aviation industry is also highly regulated in the interests of safety.
These regulations cover a very wide range of areas, including aircraft maintenance standards, requiring aircraft to carry more fuel than is required so they can divert to another airport if needed and making sure that pilots are well-rested. Commercial flights are guided throughout the journey by air traffic controllers on the ground, who ensure aircraft stay on course and remain well separated from each other usually by several miles.
Air traffic controllers also assist pilots with the safest and most comfortable journey from the moment the plane begins taxiing on the runway to the point when it arrives at the gate at which point passengers disembark. A commercial aircraft has at least two people on the flight deck: the captain and the first officer. There may also be a second officer, and longer flights will have an additional captain and first officer to allow the first team time to rest. Like the captain of a ship, an airline captain has ultimate responsibility for the safety of the aircraft and everyone on board.
The captain and first officer both "fly" the plane; to clarify responsibilities, one has the role of pilot flying and the other the role of pilot monitoring. The aircraft will have a number of flight attendants, at a minimum one for every 50 seats, who are responsible for safety in the cabin. The chief flight attendant is commonly known as the purser. The following is based on a typical twin-engined jet aircraft, such as the Boeing or the Airbus A family the two most popular commercial aircraft models in service. There may be variations to this typical flight on other aircraft models, but the general sequence of events is the same.

As passengers are boarding the aircraft, the pilots are on the flight deck making last-minute checks on the weather, departure procedures, and making sure the aircraft has enough fuel and isn't overweight. Once the doors are closed, you may hear a small jet engine powering up in the tail of the aircraft. This is the auxiliary power unit APU , which provides power to the aircraft so the ground supply can be disconnected; it also supplies the compressed air needed to start the main engines.
A tug will push the aircraft backwards out of the gate. When the aircraft is clear of the gate and the tug disconnected, the pilot will be given permission to start the main engines. During pushback, a demonstration will take place to inform passengers of the safety features of the aircraft and their use.
How Fear Works
This may be given either by the flight attendants or through screening a video. A basic safety demonstration includes the use of the seatbelts, safely stowing luggage, use of the emergency oxygen masks, location and use of life jackets, emergency exit locations, a reminder that the flight is non-smoking, to put electronic devices in flight mode and turn them off for takeoff, and that further safety information can be found on the card in your seat pocket or printed on the seats or by asking a flight attendant. If you happen to be sitting in an exit row, you will also receive instructions from the flight attendants on how to operate the exit in case of an emergency evacuation.
