What went wrong here please? Hard to tell with the critical bit just out of sight! I presume there was a crosswind from the left, but after a bobble just before touchdown it seems as though the nose was allowed to go down, or was pushed down resulting in all the smoke and slewing to port. That looked rather like the start of 'wheelbarrowing' with too much load on the nosewheel and a difficult job straightening things up. As a result the aircraft rolled out port wing high due to that crosswind not being dealt wit earlier. Is that roughly how it went ?

I have only flown much lighter machines, so maybe my description is far too simplistic. Would be interested to hear what more expert views are.

Whatever happened, it's the starboard wing that is high....

Sorry '212man' - you are quite correct that at the start of the incident it is indeed the starboard wing which is high - or more that the port wing is so low it must be perilously close to scraping the outer port engine's cowling. I meant that later in the ground roll the aircraft is rolling along with the port wing noticeably high, suggesting to me that the crosswind is lifting it. Unless there was undercarriage damage of some sort, which seems unlikely.

As 'Saintsman' says, looks like they got away with it - though maybe a short interview, hats on, no coffee, with the boss later ?

Wonder if all the rudder wagging during taxi is significant.

Looks like the rudder is just freely moving with the prevailing wind?

Looks to me like a nervous stude with the control column in a rigid death-grip cocking up a moderate crosswind landing. There is a noticeable snatch upwards or check of the nose while the wheels are still visible followed by it being lowered again (incorrectly, imho) which leads into the excursion that looks rather wheel-barrow-ish to me. There seems to be much flailing of the rudder and late deployment of the ground spoilers as there is no weight on the main gear for a while after 'landing' so the wings retain unwanted lift longer than usual. At that point, nosewheel on, crossed controls to decrab but stil 'flying' the PF prematurely releases pressure on the (right) rudder or overdoes the wing down and an excursion and wing-drop to the left immediately occurs. The use of rudder looks panicky rather than positive and measured.
Easily done.

Well, No 2 pod was scraped. So they replced the nacelle panel with one borrowed from a KC 135

Yep, details here and piccies

The yaw on touch down would indicate a brake induced yaw . Feet to high on the pedals ? Frozen brakes ? Parking brakes set ? Wrong grease used on bearings ? They did a great job to keep it on the runway after that yaw gripping event and got lucky they did not blow out the wheels and start tumbling .

The building obscured the reason for the pitch down , might have been an over correction to push it on the runway . Just pure speculation about the brakes as I have seen the results of wild landings where brakes were involved . Usually the tire flat spots with brakes on or blow the tires right out are the biggest clue as to a brake issue .
When the brakes are frozen the tires usually blow . Hence a heavy landing is a recommendation to break the ice if frozen brakes are suspected .

They could have just been practicing or simulating carrier landing techniques . Hard to see the control inputs on that video due to the building .
