I mean the boat is located 90 minutes from Cairo. It’s not easy but Cairo has skyscrapers and a construction industry.
Of course there is the “what is physically possible” and “what is politically doable” and there maybe a bit of a gulf there.

Hell, Israel's close by, and I'm pretty sure they've got this sort of airpower in droves and are probably pretty heavily reliant on the Suez Canal; maybe instead of fighting with Egypt the Israelis could, say, pitch in and foster some good will? And further, it'll make up for the time when fighting between the two countries caused a Suez Canal blockage ;)
In this case, you're Israel, your neighbor's Egypt, the street is the Suez Canal, the semi is a giant container ship, and your F-650 is about 23 CH-53-derived heavy-lifting helicopters.
Yeah, average. That doesn't mean that every container - or even most containers - are loaded to that weight per TEU. Indeed, it's highly likely that they're not; the heavy containers are going to be toward the bottom, and the lighter containers are going to be toward the top. And there are probably a lot more light containers than heavy ones, because...
> Nearly all containers are packed to the brim
Volumetrically, yes. Not necessarily in terms of weight. Indeed, unless you're shipping gold ingots or something, "max goods shipped" necessarily means that you're more likely to run into volumetric limits first.
Not to mention that the max container weight in practice is usually a fair bit lower than the ISO spec, since those containers have to get to their destination - which means traveling on roads and railways with their own weight limits (both for the whole vehicle and per-axle), and on vehicles that themselves are part of that limit (and themselves have limits of their own). And further, a container can only have so much weight stacked on top of it.
> Real life is not pleasant to armchair theory.
Indeed it is not, which is why when it comes to the containers themselves I'm speaking from experience as a professional in the supply chain / logistics field :)
(But yes, admittedly my knowledge on military helicopters is less substantial, so if there's someone who's not an armchair theorist on that topic who wants to chime in, that'd be most welcome)
Also, while we're at it w/ terrible analogies, consider that many people (including the CEO of the company that got called to clean up this mess) are saying this is going to take weeks. The more accurate analogy is that your F-650 is a dozen tugboats, the truck is not blocking the road, but instead sunk in a marsh an hour away from town (the suez sand bank), loaded w/ 10,000 50lb lead anvils (the containers) and all the manpower you are able to summon in order to move those anvils are a dozen highly paid software engineers (the choppers) who may or may not be inclined to take a week off to help you move the anvils off the truck, and who may or may not be actually physically capable of helping even if they wanted to spend their week hauling hundreds of 50lb anvils by hand. Oh, and you can't just drop anvils in the marsh either, even by accident, due to the risk of poisoning the water supply for the town. And you can't rule out the risk of one of the software engineers tripping and drowning. And you're not even sure your F-650 can pull the truck out without tumbling it on its side or yanking off the front axle even if you empty it out completely.
Also, if they find this is feasible, you don't necessarily need Israel to get a few Sikorsky choppers there, at least the Incirlik air base must have some and the Sikorsky definitely has the operational range to cross over there on its own, Iran certainly has some, the Eisenhower last I checked a few weeks ago was near Italy and surely that group has at least a few Sea Dragons...
1. This assumes that the containers are actually loaded to their maximum gross weight. That doesn't seem likely; you're much more likely to run out of volume first - even if you're deliberately "optimizing" for as much weight in those containers as possible.
1a. This assumes that the heavy containers are at the top rather than the bottom, which would be backwards from how containers are supposed to be stacked (or even allowed to be stacked per your average safety guidelines around center of mass, stack limits, etc.).
2. This assumes that multiple helicopters can't work in tandem (which they can, from what I understand).
So yeah, even if there are some containers that are too heavy to safely unload via helicopter, I strongly suspect that quite a few - most, probably - of those containers could be readily unloaded. And further, even if that ain't enough to get the ship moving again, it's at least a good start.
> the Eisenhower last I checked a few weeks ago was near Italy and surely that group has at least a few Sea Dragons...
Even better.
Do you mean two helicopters carrying a single slung load? That is not practised anywhere.
Tandem loads in military terms refer to a single helicopter carrying two slung loads, one in front of the other.
As far as I know, none of the helicopters mentioned above are rated for sling operations with 40ft containers.
There was a sea basing study and that only looked at 20ft containers and dismissed even a theoretical upgraded CH-53X (although of course the study was looking at much longer range than just lifting it and putting it back down) but again, that was just 20ft, these 40ft ones are just too heavy for choppers.

> For many containers, using helicopters would probably mean at least partially unloading their cargo, which is a difficult and time-consuming endeavor. The process of removing containers by helicopters would be even more difficult, dangerous, and time-consuming, so it is very, very unlikely we will see it implemented unless the situation gets really desperate.
