India has many crews who, whilst having paid for their licences, certainly didn't earn them. The corruption within the DGCA has been widely reported.

From what I heard At lift off the captain's seat got seat moved back from its position resulting in yoke going up and in reflex captain pushed the yoke which pushed the aircraft's nose down, resulting in these unfortunate incident.

Not a piiot here, but looking at the pic on BBC report, the belly gash looks to be situated between the L/R MLG, not further aft.

Reports suggest that it was the belly of the aircraft that hit the localizer antenna, but the question asked was what had impacted the wall, which was the rear fuselage.

I'm not sure how that would be consistent with the crew "not noticing anything wrong". (Not saying that this isn't true, just it's inconsistent with the reported crew "relaxed position" about nothing being amiss.

So the scenario is the aircraft somehow gets upset at rotation (seat movement, whatever) and ends up being far too low and rips out the belly on the antennas, then the crew yanks back and presents the belly to the wall/fence? Except there's photos purporting to show elements of the fence (atop the wall) embedded onto the gear struts. So the gear hit something roundabout then too... I think "they were damned lucky" is about all we can really conclude!

How could it pressurize with those gashes?

This is the best view I've found of the wall.

that explains a lot. Wheels hit the wall. Gash from the localiser.

Good find.

That seems to negate the earlier suggestion that the two holes in the wall were too close together to have been produced by the mains - they appear to be consistent with the 737NG's track (5.72 m).

tonytales,

By the look of damage from the existing photos on here, it is only superficial damage in and around the wheel wells and keel beam area and the fuselage pressure vessel has not been punctured/ruptured hence no loss of pressurisation (that we know of ???) By the look of the damage on the brick wall, I'd say both gears came into contact with the wall. Soooooo lucky that this was not a disastrous outcome!!!

McHale.

Can anyone run these numbers? 738, trip length 1590nm/2491km, runway length 2427m/7963 feet, OAT 83F/23C.

There is a great deal of aeroplane outside the pressure vessel.

The picture of the wall says either a lot about the strength of Mr Boeing's aircraft or not a lot about the building skills of Indian bricklayers.

Did the wheels actually strike the wall or did they catch the chain link wire pulling out the supports and the sections of the wall they were embedded into?

One does not exclude the other.
