No.3 would be the engine on the starboard wing. They are counted from port to starboard.

I think the cowling of the departed no.1 engine ended up the other side of the runway so quite possible it killed no.3.

However, one of the videos shows no. 2 at the back spitting out sparks just after rotation. It quite possibly ingested fire from the burning port wing at that point.

......
but the cop cars I have seen are unmarked and all you get to see is the blue lights hidden behind the grills when they start to flash with the headlights when they are in pursuit.

Unless you have Target Blu Eye fitted (TETRA Comms detection), and then you'd know they were there from half a mile away. 

One thing I did learn on my patronisation course is the sort of distances their gear works over.  Not sure half a mile would be enough 

My last set of points were picked up at just under 700m, as I came over the brow of a hill


And, yes, I am a reformed character, and I was officially doing less than 70mph on a rural dual carriageway.  Its just I refuse point blank to obey HS2's stupid road speed limits they have whilst they spend 4 years to build a single bridge.  There is no need for the speed restriction, as, lets face it, they are definately "working out of sight", just not anywhere near the bloody unfinished bridge.

Ahh! The invisible builders again! The same ones who are Pi$$ing about for years at the M25/A3 junction.

All slats and spoilers do is change the shape of the wing as required to maximise lift/reduce drag at any given airspeed. Note that drag is not the opposite of lift.

You say that as if they are insignificant. The significant thing they do is to reduce the stall speed of the wing so that the aircraft can operate at the lower airspeeds used during approach and the initial climb.That can come at a significant cost in terms of drag too with some configurations, but that is actually an advantage on approach, because you need to be able to shed energy and the engines are kept at a higher thrust setting and can respond faster if a go-around is initiated.

The two things they needed they didn't have... Airspeed and altitude. The wings will always provide lift as long as there is air flowing over it. Removing thrust on one side causes a loss of airspeed over that wing. Less airspeed equals less lift. Likewise the yaw induced by the loss of balanced thrust further slows the unpowered wing causing more loss of lift. As the wing drops the aircraft will always roll to that side. Once the left wing touched the lift from the working wing finished the roll.

Yes, but all of these effects of asymmetric thrust are possible to counter with control inputs until the wing stalls, which didn't happen in this incident, judging by the footage I've seen, but did, almost instantly, for AA191 due to slat retraction below the clean stalling speed. I'd say the crew in this case did a great job of keeping the aircraft flying to the crash site. Sadly, it didn't help them or the souls on the ground.

This has happened before on a DC10

Do you mean This one?

If so you'd hope that the lesson of not fuŁking about with the manufacturer's maintenance procedures had been well learned! 

The only similarities are aerodynamic consequence. Erase that engine and it's thrust and the resultant roll is swift and catastrophic and will happen every single time.

Incidentally, not many operators own any and fleet utilisation is pretty low...

https://en.wikipedia.org/wiki/List_of_McDonnell_Douglas_MD-11_operators

The main issue with AA191's loss of control was retraction of the slats on the port wing and the consequent asymmetric stall due to hydraulic damage, an issue that was countered by an AD in response to the crash investigation.

There's no roll I can see on the videos of this crash, at least not until the port wing contacts something solid on the ground and the airframe cartwheels.

Aerodynamically, it's an engine failure, so possible to counter with control inputs assuming you still have a working system by which to make them.

Add a load of fire and a second engine failure and there is, of course, no hope.

I see they are frothing over today because one of their presenters used the expression "pregnant women" instead of "pregnant people".

One problem with the Trijet configuration is that No. 2's intake is prone to ingesting disturbed air / debris if anything happens to 1 & 3, especially after rotation when the wing is working hard.

With that amount of fire, engine thrust might have been moot, however. I wonder if there would have been enough left of the wing structure for it to remain controllable for a go-around even if it had climbed away.

Thoughts of the AF Concorde crash come to mind.

It would take quite a bird strike to rip an engine off its pylon and dump it by the runway, but it's not impossible that one started the whole chain of events, I suppose.

The only saving grace is that they didn't suffer it for long

.. and that it was full of Amazon packages not passengers and more crew.

Horrendous crash. Clearly a serious uncontained engine failure or something similar. I feel for the crew and anyone in its path on the ground. Once that hit V1 their fate was sealed and they just got to watch it unfold before them.

He is a JP, so a man of impeccable judgement.

I met quite a few JP's in my younger days, and none of them were very nice to me.    They always fined me for trivial things.     I mean, what is the harm in a 16 year old popping to the village chippy on his Moto X bike.   

Bad for your cholesterol, presumably?

Is it still legal to shove lit bangers up a cats arse and see what happens?

Pretty sure it used to be.....

My poor moggies have to stay in this time of year when it gets dark, to stop the mongrel, uncontrolled kids doing just that.

Whereas I'd like to see them try that with our cat.. I suspect they would end up crying..

Apparently, he was eating a packet of ready salted crisps, which the police mistook for an improvised explosive device. They drew their tasers and shouted "Police officers with tasers, show us your hands". He looked up in surprise and dropped his crisps. The police officers hit the deck in anticipation of a large explosion and an armed support group officer, who had been feeding the ducks, shot him dead where he sat.
That'll learn him. 

He can't wait to go home.

I hope they got him for littering too. Not sure what he'll do for comedy when he's back home. We've got far better wombles here...

I have one to go to the tip too. Even breaking the bead on a modern tyre is a challenge in DIY land let alone tyre levers!

I can see sales of Doro phones picking up significantly if this comes to pass.
