Helicopter crash

Helicopter is just the same as a plane, it’s aerodynamic lift that makes it lift off, just on a helicopter the wings(rotor) are rotating and on a plane the engine(s) are pushing them through the air.

Wrong. On all points I'm afraid. It certainly is not the same aerodynamics as an aircraft. One has uplift one has airlift to get them airborne. Both use the engine to generate power enough to defy gravity but in a completely different way. which is why a helicopter in trouble from taking off, is in so much more trouble than an aircraft.

wait..which one is stable? both crash. 

Assuming both types of aircraft are functioning properly, a fixed wing plane will be stable if airspeed is maintained. A helicopter wants to auto-gyrate (yaw) and fall out of the sky  (gravity), so only the constant trimming of the blades on the overhead and rear rotors will stabilize these forces. In which case the fixed wing is inherently stable the rotary wing aircraft is not. 

Something I didn't know until today, is that the overhead blades not only vary in pitch from full to flat in one revolution but they also flap up and down. As you can imagine, that is an extremely complicated configuration and I imagine, subject to enormous forces with attendant wear characteristics.

Not the time for an argument but I speak as a pilot  of 20 years with PPL, IMC & NR.

 

From NASA website;

 

In order to fly, an object must have "lift," a force moving it upward. ... A helicopter'srotor blades are wings and create lift. An airplane must fly fast to move enough air over its wings to provide lift. A helicopter moves air over its rotor by spinning its blades.21 May 2014

New video showing Helicopter spinning out of control just out....

 

Contains footage most will find distressing, but thought id post as it in the mainstream media now

No need for argument here. Anyone with experience of flying knows that helicopters are very different from planes. They work in very different ways. They attain lift in a different way, even if there are some vague similarities. 

 

If the tail rotor of a helicopter fails it is nearly always catastrophic. The pilot of Vichai’s helicopter pulled off the almost impossible. He got it down in about the only safe spot for ground casualties available to him. The terrible thing is that he was within an ace of getting it down in a manner that might have afforded a reasonable chance of escape for the occupants. It is truly heart rending.

Really think this stuff should be kept off the forum.

 

But I will say, someone working at the stadium filmed that, and sent it to the sun, that is ****ing disgusting. Im glad it wasn't anyone I knew who was there at the time.

Don’t know why people send this footage to the tabloids instead of investigators. Hope they’re proud of the money they received capturing someone’s death on camera.

At least the club will be able to identify him extremely easily. Sent it to my girlfriend, she's pretty sure she knows who it is

If this is a club employee then it is absolutely disgusting.

Sold his soul, trust the scummy sun to buy  it 

[KFS]

Anyone with any knowledge know how that even happens? It looked fine going up and then all of a sudden just loses control? I’m really confused and feel a bit sick.

It absolutely is, only people who would still be there. Plus where they are standing, just outside the players tunnel, is where ONLY high level staff or security can stand at that time. Cleaners etc watch from the stands.

 

I hope he sent it to a friend who has leaked it and not himself. Having said that, just filming is against their contract, so he's still ****ed.

I heard the engine packed in once airborne but watching that video it sounded like it was still running.

Is the puff of smoke at the start normal?, its a hard watch

Sure the club would paid a certain amount to keep it out of the media if they knew it was going to be leaked, as a mark of respect

Mechanical fault. Sometimes they visually can't be spotted on checks.

I thought about watching it long and hard, but chose not to in the obvious respect to the victims.

Yes don’t if you don’t have to. I personally deal with these things with details. It helps me picture and then put it to bed.

 

Not that selling this to the Sun is in any way acceptable.

Pretty sure that’s just st a normal start up.

Looks like the tail rotor just packed up ...   couldn’t see any foreign bodies (birds drones etc) so presume it was a mechanical fault ...   the pilot would have had little control to direct where it hit the ground but if the story is true that he gestured to the guy who ran to help to get away as it was going to blow then he is one bloody hero ...   imo.

i feel queasy just reading that it made you guys feel sick, can't bring myself to watch it

Don’t 

[Gillies Apprentice]

I’ve not watched it ,but some friends and family have and wish they hadn’t .Surely it should be taken offline as it graphically shows people about to die horrifically .
