What about this landing technique day before yesterday? Good only to land on carriers where there is hardly any crosswind ? Why after touch down this pilot still corrects the wind by crab ONLY, what about those poor tires...

Good job. Right on the spot and cleaned the oleos as well. :D

When I were an F/O I used to fly with ex RN and Army Captains who complained about it too.:)

From Boeing FCTM:

Touchdown in Crab

The airplane can land using crab only (zero sideslip) up to the landing crosswind guideline speeds. (See the landing crosswind guidelines table)

On dry runways, upon touchdown the airplane tracks toward the upwind edge of the runway while de-crabbing to align with the runway. Immediate upwind aileron is needed to ensure the wings remain level while rudder is needed to track the runway centerline. The greater the amount of crab at touchdown, the larger the lateral deviation from the point of touchdown. For this reason, touchdown in a crab only condition is not recommended when landing on a dry runway in strong crosswinds. On very slippery runways, landing the airplane using crab only reduces drift toward the downwind side at touchdown, permits rapid operation of spoilers and autobrakes because all main gears touchdown simultaneously, and may reduce pilot workload since the airplane does not have to be de-crabbed before touchdown. However, proper rudder and upwind aileron must be applied after touchdown to ensure directional control is maintained.

It LOOKS bad but, without the data or loading counts it is hard to be specific. Speculating on the video, they look to encounter a strong gust at about 0.24, and very variable conditions through to the first touchdown(s), the bounced landing and the final, almost 3-point landing (which may have been the firmest).
They were about 100' when they encountered the gust, worth a G/A?:ok:

I wouldn't recommend that on a 6. Side braces are their for a reason.

Once upon a time many pilots claimed their goal was to retire and leave with the Chief pilot saying "who?" .

Nowadays I guess the aim is retire without appearing on YouTube and having a landing dissected on social media......

I've got away with it so far.....:} :)

A static pressure sensor?

I believe it is indeed a trailing cone pressure sensor - the parachute/cone pulls the sensor well away from the aircraft.

many years ago, while reading "stick and rudder" WL gives a good reason not to have rudders on planes and that landing in a crab will work out fine in a nosewheel plane.


crab, take some out near the end if you can, and if you can't, you probably won't get too hurt if you have tricycle gear.

Unless you land on the nosewheel! See the ANA!:\

No disrespect to the DC10 crew.

I dunno - I'd rate that videoed landing at least a 7 out of 10. :D

Looks like gusty conditions - a gust can drop you faster than your can respond, and the crew handled the bounce gracefully (mains touch down second time about 1 second before the nosewheel - which is better than vice versa).

I'd actually give the crew high marks for not horsing the controls around in pitch to "correct" the bounce, and ending up with a nose-plant or a second bounce or a tailstrike. A gentle touch was enough.

The "crab" after landing looks more like a little weathervaning by the aircraft in another gust, rather than pilot input.

73NG fail-passive autoland impacts with up to 15kts X-wind without drift being removed, so the 'frame copes with the first 15 knots without distress. Tell that to your F/Os and then they hopefully won't get so sweaty when the actual weather report is received on the approach?

The video looks like a lot more than 15kts and I suspect the poor driver was thinking of squeezing off the crab before touchdown when it happened.

Could happen to Boeing or 'Bus but most of the time the company can use the plane again immediately so it would then be defined as a "great" landing!

Check rudder inputs just prior to touchdown. Seven movements, left, neutral, left, neutral, etc, etc, in 7 seconds. Gusts aren't that rapid.

20 kts now even.. I think it changed a year or two ago in our limitation section.
