JetBlue, Boston's largest carrier, grounded hundreds of flights in and out of jordan shoes stores online the busy Northeast corridor on Monday and Tuesday, at one jordan shoes new york point entirely shutting down its operations at JFK and jordan shoes montague gardens Logan. Other airlines too have grounded flights, stranding thousands of passengers jordan shoes that come out saturday at airports in Boston, New York, Toronto, Chicago and elsewhere, as unusually cold temperatures, spawned by something meteorologists call a "polar vortex,air yeezy 2 red october price," roars across the country.
But the cold weather is only part of what's been happening. The jordan shoes men retro 13 cancellations and delays are the result of an unusual confluence of events a perfect storm if you will (much as I hate that expression), of four separate things:
Let's take that last one first. A new body of rules, intended to combat fatigue, went into effect on January 1,discount jordan tc shoes, jordan shoes new releases limiting the number of hours flight crews can remain aloft or on duty. Sure, the airline industry had more than a year to prepare for this implementation, but bear jordan shoes women retro in mind the vastness of a major carrier's operations, with thousands of pilots operating thousands of flights each day. Those are a lot of moving parts, and the revised rules are quite complicated, with changes to flight time restrictions, duty time restrictions, minimum layover times, and so on (always count on the FAA to over engineer a solution). One airline's informational packet,nike air yeezy glow, handed out to crews to assist them in deciphering and working with the changes,jordan tc black sale, is over fifty pages michael jordan shoes pictures long. The learning curve will be steep. Despite the lead up time, it was impossible to know for sure how jordan shoes in men the new regulations would affect things particularly when, on the very first weekend they took effect, stormy and freezing weather began pummeling some of the nation's busiest airports.
Ice and snow need to be dealt with regardless of the temperature. Aircraft need to jordan shoes gray be jordan shoes price philippines free jordan shoes information of contamination, and runways and taxiways need to be clear. (For everything you never needed to know about icing and deicing, see chapter three of my book.) But while ice jordan shoes vip and snow were a problem over the weekend, the trouble over the past few days has been the cold. How is it that planes are being grounded simply jordan shoes tokai from cold? After all, it's about 60 degrees below zero at 39,000 feet. Why would sub freezing temperatures prevent a plane from flying?
Well they wouldn't. If anything, airplanes perform better in cold weather jordan shoes head office than in hot weather. Some planes do have limits that prohibit operation when ground temperatures fall below a certain point (the complications here involve starting the engines, cold soaked oil and such), but that's not the issue here. This isn't about a plane's ability to fly. It's about the weather's impact on the support infrastructure. That is, airport personnel and the ground support equipment jordan shoes materials the various people, vehicles and machinery that go into supporting an airline's operation. You can't load and unload the luggage, fuel the tanks or cater the cabins if the baggage carts jordan shoes red white reofer4 $48.00 and belt loaders aren't working, the trucks aren't starting, and employees are so cold they can hardly move.
Meanwhile, airlines are becoming more and more conservative when bad weather looms, preemptively readjusting their schedules before the brunt of any storm actually move in. This is highly unfortunate if you're one of the many people jordan shoes all styles whose flight is delayed or canceled, and you find yourself sleeping under a bench in the terminal, but things would likely be a lot worse,cheap jordan tc cool, for an even greater number of people, had the airline michael jordan shoes release dates attempted to push through. And remember that planes don't simply fly back and forth between the same two cities; what happens in Boston or New York jordan shoes official site affects flights, and their passengers, further down the chain, in cities across the nation and the world. Drawing down the operation here helps protect those passengers elsewhere.
Like so much in commercial aviation, it's never as simple as it seems. A crisis, an accident almost always it's the result of multiple factors; a compounding of things gone wrong.
