Came to say the same thing. Done in one.

Doesn't look like 8' over their heads. Maybe it's just the angle and they've both got super long arms.

My bravery ends at putting a stool out there, and wishing the pilot "good luck."

I have never understood retractable landing gear on helicopters. Any improvement in drag coefficient would be lost in weight gain.

Skids do not allow for taxiing and retracting the landing gear is a fair improvement in fuel efficiency and, perhaps more importantly, flight stability. Wind could also shear off or damage any exposed system. This is a long haul passenger chopper, the kind they use to ferry personnel to and from oil rigs.

Impressive.

Is that what it takes? I always wondered what it took.

If they hadn't changed that tire, the aircraft could have gone into "Ground Resonance".  A helicopter in ground resonance will quickly shake itself apart in a particularly violent event.

Sigh... I've got Duke Nuke'em Whenever somewhere around here. New in shrink wrap, found at a thrift store. Need to play it some time.

Oh yeah, I agree that the use of landing gear is superior to skids. However retractable gear is heavier and adds unnecessary complication to what should be kept as simple as possible.

Here is a CH-47 Chinook landing gear:

airforceworld.com

Notice that it is non-retractable, and yet the aircraft still has a VNE (Velocity Never Exceed) of 174 knots, or over 210 mph. Retractable gear requires hydraulic lines, and makes it non-modular.

The fuel savings that rolling take-offs and landings afford, are considerable. Even a five-foot roll can save many gallons of fuel. On a Chinook, the landing gear are kept as simple as possible. Only the rear set may swivel, and only one rear wheel is steerable, the other simply goes where the steerable wheel moves it.

In this image, the man on the right is using a grounding hook to electrically ground the aircraft. I've seen static electricity jump over a foot and knock a hook-man right off a load in the right conditions, so it's good to see that these guys are doing their job correctly.

Came here expecting breathless commentary from Fark insta-helicopter 'experts'.

Leaving satisfied.

That is what I thought.

I thought helps needed to be grounded or you would be shocked to shiat.

I don't see any grounding on the one in the article.

Yeah, it's funny, but every time you see a hook team doing it properly, it's almost always an infantry or engineer group. They'll break out the manuals and do it correctly, because it's new to them. Aviation units almost always take dangerous shortcuts, because they know it all.

I've never had to reject a load rigged by a non-aviation unit, but I've rejected many rigged by my sister-units.

So what happens when helicopters don't have tires, but skids instead?

Holy HELL, is that ever an obscure reference!  I need to see that again sometime.


I loved that episode. It's the only one I even remember.
