These reactionsâknown as the âstress responseââinclude increased heart rate, a rise in blood sugar, more blood flow to the joints and muscles, and faster blood clotting to reduce the chance of blood loss after an injury. The adrenal glands also produce more cortisol, which can have a major affect on the body.hen a person experiences constant physical or emotional stress, the adrenals are constantly responding to this and working much harder than normal.

However, we're still left with figuring the cost of the 5.5 gallons of jet fuel, and that again depends on what price the operator is able to buy the fuel at. Today's fuel prices, depending on where and when it was purchased, can range from $3.50 to $5.50 per gallon and more.So, if we guess at an average of $5 per gallon, we get a cost for fuel of $27.50 per mile.This is a very rough figure for fuel costs only, and doesn't include any of the many other costs associated with operating the aircraft.Hope that helps some... 15 people found this useful.   To give you a rough idea, however, we can look at fuel cost per mile for a 747-400 Freighter. Average fuel usage is around 3,200 gph and it cruises at around 585 mph, so a rough average fuel usage for a 747 would work out to around 5.5 gallons per mile.
