Humans are land animals, evolved to exist comfortably close to sea level at amaximum speed (and that for only very short sprints) of little more than 15 miles perhour. Jet aircraft are designed to operate efficiently at high altitudes but the human bodyis not. Rarely do we think about the temperature outside orthe time available to react should our carefully maintained environment fail.

We sit in shirtsleeves, comfortably oblivious to the frigid and rare atmospherethrough which our fragile shell moves. We spend many hours inour carefully conditioned cockpits, only inches from an environment that is incompatiblewith life. Usually lessthan half will have taken advantage of this valuable opportunity. I am always amazed when I ask a class of experienced jet pilots undergoing recurrenttraining how many have been through the FAA’s physiological training program. Before we look at the airplane itself, let’slook at the environment it was flying in. So, what could have happened to that Lear? Did it have any inherent weaknesses? Werethere procedures that weren’t followed? Again, we may never know, although the NTSB hassome powerful forensic talent and resources.

How long do flies live from their own viewpoint, if their world is in slow motion? That question remains unanswered, but if you have a fly infestation in your home, speed the process of elimination and call Terminix®. They have the ability to see objects up to four times faster than humans, meaning that a newspaper swat from their view happens in slow motion. However, flies have a different perception of time than humans do. How long does a fly live? Most flies live between 15 and 25 days. The pupal stage lasts four to six days in warm temperatures. It is during this stage that the white, characterless maggot begins to take the form of an adult fly.

The larval stage is followed by the pupal stage. Each stage takes anywhere from three days (in temperatures above 80 degrees Fahrenheit) to eight weeks (in cooler climates). Maggots grow rapidly and must molt, or shed a layer of skin, before each larval stage. During this part of the fly life cycle, larvae are also referred to as maggots. She can lay an estimated five or six batches of eggs during her lifetime, starting on average, about 12 days after reaching full maturity.Įggs take eight to 20 hours to hatch and reach the first of three larval stages. The life cycle of a fly begins with the egg. The female house fly can lay anywhere from 75 to 150 eggs in a batch. House flies have an incredible ability to reproduce, however, the fly lifespan is typically short. These stages move from eggs to larvae and pupae to adult. Like all other flies, they develop through a process called complete metamorphosis. House flies are one of the most commonly recognized and widespread insects in all of the world.
