Strange Landing with Early Reverse

hi guys!
i'm not a real pilot but i want to be and i though that i know something about that, but i can't explain how that pilot did that landing without sudden quake

Please correct me if I'm wrong here, but aren't western built aircraft designed so the TR's can not be opened unless the WOW switch is activated so this can not happen in flight?

That aircraft is a Russian-built TU-154 that has the ability to do that. I don't know much more than that (I'm sure you can search somewhere for answers) but I would imagine they act just as speedbrakes until landing at which point the TRs kick in.

Here's a better picture

I was going to say it's a Tu-134. I like the little tailskid wheels.

I can't imagine they did that on purpose, but I guess a hard touchdown must be something they like.

Just to clarify...the jet isn't actually reversing, they just open the buckets and use them as a speed brake to negate the idle thrust on those two engines.

A bunch of airplanes have had this idle reverse thrust capability (HS-121, C-17, Tu-154) but the only one i've ever heard of actually being able to apply reverse thrust in flight is the NASA G2.

And the C-130 being able to go into Beta while still weight off wheels that landed on the carrier

A little off topic, but can't you do the same thing in the DC-8 ?

Yes, you can reverse the inboards (#2 and #3) inflight, but it is hard on the pylons. I've been told that if you were to see the engines from inside the airplane when you do this, they are shaking, twisting, and vibrating in a way that would give you the heebee-jeebies. At UPS, we had a specific speed and altitude envelope that this could be used, which was more restrictive than the AFM. I only did it once - as an example of how it works during IOE. It was stressed that your descent planning should be accomplished in a way that you didn't have to do this.

Now, if you were to do this in the flare...

You may end up as a smoking hole...
