Roadside service for a Commercial Airliner

In the November 2008 issue of Air & Space (Smithsonian) Magazine had an interesting article on Boeing's Aircraft on Ground (AOG) team. The author was able to follow the team as they repaired a Boeing 767 that had been damaged when it had been backed into a jet blast fence and the rear pressure bulkhead had been punctured.

[Air & Space said that they were asked not to disclose whose airliner this was and what airport that this took place at]

Here's a picture from Boeing - showing the vertical stabilizer being put back on (contrary to the caption). If this was the only picture you saw - you wouldn't know that the caption was wrong. I'll explain how I can tell in a minute - the hint is in the lower left hand corner of the picture.

This past weekend on the National Geographic channel - their (HGC) series "World's Toughest Fixes" featured this specific 'fix'. NGC wasn't nearly as shy about saying where this was all taking place. It was in Paris, at Charles DeGaulle airport. The damage occurred on Chrismas Eve (2007).

If you can catch this episode either this week or in repeats - set the Tivo/DVR for it. Its interesting to see what goes into a job like this. If you don't get NatGeo or don't have the time for it - click here - for a quick 2 minute summary of the repair.

Ok - so back to that first picture. The lower left hand corner is a video camera (filming the NGC episode), and the green section of the underside of the fuselage is what gives this picture away as being post-repair. That green section of the fuselage is the section of skin that was replaced as part of the repair.

Also - look at this picture - showing the pressure bulkhead being replaced - the guy on the right in the red hat is the host of "World's Toughest Fixes." You can pick him out because he is the only one with chest pouch/toolkit.

Finally - to answer the question 'whose airliner was this' - I present links to two pictures;

• Flickr
• Airliners.net

It actually wasn't too hard to find pictures matching this airline livery on-line. The TV show helped somewhat - when they had a close up of the vertical stablizer being put into its temp cradle - you could see what looked like two white birds in flight (in between the red and green fields).

BTW - the airline really wanted to get the plane back in the air. They only have two 767's in service. So while this one was laid up for 3 weeks - they long range fleet was at 1/2 capacity.

How to - make your own QR Code

[if you watch CSI:NY on CBS, the episode last week featured QR codes on the back of the 'tell all' stationary that was part of the murder investigation]

I have already shown how you can decode a QR code - and now you want to create a QR code of your own. Start by going to the Google Chart API developers guide. In addition to the standard line charts, bar charts, pie charts, Venn diagrams and maps - the Google Chart API also supports QR codes.

You call the API just as you would call any other image that you would link to;

http://chart.apis.google.com/chart?cht=qr&chl=URL:http://www.strongholddigitalservices.com&choe=utf-8&chs=200x200&chld=Q|10

• Chart AP - http://chart.apis.google.com/chart?
• Chart type - cht=qr
• Data to encode - chl=URL:http://www.strongholddigitalservices.com
• Encoding - choe=utf-8
• Size (in pixels) - chs=200x200
• Error correction | margin - chld=H|5

Note - the amount of data will determine how many bits are in the QR code. The size just determines how big the output will be.

The Error correction letter says defines how much of the QR code can be missing or obscured, while still allowing the data to be retrieved. The 'H' code allows up to 30% of the image to be missing or obscured, and still able to maintain the data.

Here are some samples to illustrate the differences.

Size 200x200, Error Correction = H


Size 100x100, Error Correction = H



Size 200x200, Error Correction = L (worst, only 7% error/missing/obscure)

All three images contain the exact same data - but they differ only in size (between 1st and 2nd) and data correction (1st and 3rd).

Now - why has Google gone to such trouble to include the QR code in their Chart library? I don't know for sure - but it happens to be part of their Android mobile phone OS on TMobile's G1 handset. Beyond that - we will have to see if these start showing up and get adopted by more than just the twenty-something's.
