There are potentially other variables that would make quite a big difference though.

Yah - understood. But not inherently a tight squeeze. Thanks.

From that clip, it looks like the main gear caught the top of the wall. Someone on scene with a measuring tape should check the distance between the two notches against the gear's width. Another photo (posted above) looks like some scuff marks on the inside of a tire.

The bare, apparently undamaged, fence posts on either side of the damage seem to indicate that fence wasn't attached all that tightly. That suggests that the tires hit the masonry directly. But the fence could have been attached differently to different poles, I guess.

This was done deliberately to guard against tripping up any tardy take offs......

Wow, the second page of that story ( https://www.flightglobal.com/pdfarch...0-%203938.html ) is quite something!

Thankfully the son retired last year (finally) after 25,000 incident and accident free hours! Funny how his past kept coming back. Any former friends at KAL like to comment on the man who could talk under wet cement? Certainly Johnny Sadiq makes a wonderful reference to him in his book “Come Fly with me: Jets”.

Just as well Boeing still build strong airplanes!

Why do India and some other countries build walls around airports . They are an obvious hazard .

Brilliant!

How far do you want to go from the end of a runway before allowing a small wall to be built?

Apparently the inside news is that, as received from a friend in AI. The captain's seat got unlocked during the T/O roll and moved fully back. He got pulled back, control column was initially pulled then pushed fully forward. F/O took over and rotated at end of runway. I guess someone at mx will be scratching their heads now..

The really big problem here is not the fact that they hit the localiser and/or wall. Or why they did so. The huge problem is that they initially continued toward Dubai, at FL360, despite the huge damage to the aircraft.
And I don’t believe any part of their story that they did not notice anything unusual during their takeoff run. Especially after all that photographic evidence.

That's what makes everybody surprised. I think the pilot's tried to save themselves by continuing their flight.

You are not supposed to be still in ground effect at the end of the runway! They took out equipment before they hit the wall anyway..

underfire 14th Oct 2018 16:38

obstacles are to be below the 50:1 plane from the end of the runway. In many places there are walls to protect the airport grounds.

krismiler 15th Oct 2018 00:47

In the MK Airlines crash in Halifax in 2004, the rear fuselage struck an earth berm supporting the localizer antennae 300 m beyond the end of the runway. This caused the rear fuselage to separate from the aircraft. Had the wall in Trichy been more a more substantial obstacle, we could have been looking at a repeat. Unfortunately airports can't always be built in ideal locations, the boom in air travel, particularly in developing countries has resulted in many airports carrying a much higher traffic volume of larger aircraft than they were designed to. Lax urban development controls have resulted in housing encroaching closer to runways than should be allowed. Many times I've operated into an airport and thought any over run would result in a disaster.

If the explanation regarding the Captains seat is correct, the question is was there a fault in the mechanism or was it not adjusted properly prior to take off ? As I'm not a B737 pilot, could someone perhaps explain how the seat adjustment works ? Is the seat moved manually requiring a pin to lock into a hole, which would explain the seat moving backwards on rotation if it was not secured correctly, or is another method used.

Cessna seats were so bad that many aircraft had a hole drilled and a bolt installed in the guide rail, to limit rearward travel in the event that the seat came unlocked.

All the talk about the seat smells like damage control to me. When faced with the impending withdrawal of your flying privileges any excuse will do.

Indeed.

Didn't make it to Dubai. But was the flight to Mumbai long enough to overwrite the most critical portion of the CVR?

More than enough.
