What Happens When A Boeing 747 Comes To The End Of Its Working Life?

by Jessica Festa on




We talk a lot about what goes on with airplanes while they’re being used by airlines, but have you ever wondered what happens to an aircraft when it comes to the end of its working life?

Since its first commercial flight in 1970, Boeing’s 747 jumbo jet, one of the most recognized aircrafts in the industry, has been flying travelers around the world. Like all commercial airplanes, the 747 must undergo regular checks to ensure its safety and efficiency. According to Digital Trends, about every six years these airplanes undergo a complete overhaul on the inside and outside.

BBC recently looked closely into the matter, creating a documentary called “Engineering Giants.” The documentary looks at the process of a Boeing 747 refit and what happens when one reaches the end of its working life. Usually, the first step is to take everything of value out of the airplane, like cockpit screens that can go for $30,000 each and engines that sell for around $1 million. From there, it’s time to crush the plane’s shell, which takes about three days. Lastly, the twisted aluminum is sold for approximately $55,000 and recycled into drink cans, bicycle frames and other useful items.

Watch Desert Winds Pick Up And Move This Boeing 747

It’s interesting seeing the fluid dynamics of modern flight turned backwards on a stationary aircraft. Normally during takeoff, an airplane flies into the wind to create as much air movement as possible over the wings. It’s a mixture of the Bernoulli effect and a variety of other physical principles, but the end result is lift as a function of air speed.

And if the aircraft isn’t moving? Technically you can still get lift with enough air speed. Youtube user CaptainHarlock999 captured an amazing video this week in an aircraft boneyard outside of Los Angeles. With winds at the scrapyard reaching over 70MPH, enough lift was actually generated by a 747’s wings to actually pick the fuselage up off of the ground, bouncing the plane around as the back wheels stayed in place.

The Southern Air 747 in question was actually scheduled to be scrapped, so the engines and much of the interior were stripped off of the airframe. Because of that reduced weight the aircraft was able to lift off the ground — so don’t worry, it won’t happen to you on your next trip!

Airplane Engine Covering Falls Off During Takeoff (VIDEO)

by Libby Zay on

A passenger filming out an airplane window captured part of an engine cowling ripping off during takeoff on a flight in Brazil. Watch above to get an idea of how the terrified passengers – who later described the event as an “engine explosion” – must have felt watching the parts fly off. According to an incident report on The Aviation Herald, it all happened on a TAM Airlines Airbus A320-200 traveling from Natal to São Paulo on Saturday, May 19. There were 166 people on board, many of whom you can hear hurriedly asking questions and yelling during the video. According to the Herald, both the inboard and outboard fan cowl doors of the left engine opened in flight and “were ripped off.” Stay tuned until 1:54 to see the extent of the damage. In the end, the pilot managed to return to the airport in Natal without any further problems – but the passengers sure did get a scare.

House Oversight Committee requests feedback on TSA

by Grant Martin on

Public acceptance of the Transportation Security Administration (TSA) and its somewhat dubious methodologies has always been tenuous among the American public. Some feel that the technology they use is the only way to keep American travelers safe. Others feel that their power and influence reaches too far. In either case, there’s lots to say, and for once, congress appears to be listening.

On next Monday, the 26th of March, the House Oversight Committee is convening a hearing on the TSA and their recent operations. Led by Oversight Committee Chairman Darrell Issa, the meeting plans to investigate “program challenges and failures,” no doubt including recent efforts with Advanced Imaging Technology (AIT) — or 3d scanners — and other questionable measures in place.

As part of the initiative, the committee is soliciting stories via its Facebook wall for discussion during the meeting. This is a great opportunity for those with praise or complaints about the agency to voice their opinions. Even if the comments don’t get read, the sheer volume of feedback from users should provide some insight for the group. Check out the Facebook page here and leave a message — your feedback could help shape security in this country for good.

FAA reconsiders use of electronics on airplanes

by Grant Martin on

Anyone who has tried to use an e-reader or tablet on their flight in the last several years knows about the strict rules that the Federal Aviation Administration (FAA) places on their operation. Taxi, takeoff and landing are periods during which most electronics are prohibited, a rule that has riled up frequent travelers and tech lovers alike. Even “Mythbusters” has an episode exploring the use of cell phones on aircraft electronics (result: busted).

Given the changes to technologies and continuous pressure from consumers, that may soon change. The New York Times‘ Nick Bilton on the Bits blog posted an interesting article this weekend in which the FAA admitted that they’re looking into revising their policy. The current policy in place, which puts the onus of testing on the airlines, is too expensive and time consuming for the industry to support. As a result, the agency is looking into methods to “bring together electronics ‘manufacturers, consumer electronic associations, aircraft and avionics manufacturers, airlines, pilots, flight attendants and passengers’ to figure out how to allow greater use of these electronics on planes.”

There’s no word on what sort of schedule the FAA has in mind or how serious they are about the initiative, but if we can believe this report, the tide may soon be turning.
