And several possibilities (for example, with Atlas V) were wasted.

Uh oh, did someone call the USS Harry S. Truman and let them know they can turn back?

In perfect conditions as long as ship stays straight I guess it's fine but in this case they definitely got themselves in a kerfuffle and jackknifed her good! We're gonna need a bigger tugboat.
They'll probably need to bring in a large dredging ship or similar to try to get it out I imagine.

Whether they are seawater canals for huge ocean going vessels, or inland canals for vessels specifically designed for canal only use, it has always been normal for canals to carry ships longer than the width of the canal. Canals cost serious money. Making them any wider than is necessary for 2 vessels to pass each other safely would make most of them too costly to be viable.

Some canals are not even wide enough that 2 of the larger ships can pass. So they have to operate at last parts in one way mode. This is the usual way for the suez canal. They are in the process to widen the longer northern part, so that they can go both directions at the same time, at least for that part.
If the ship is much longer than the canal is wide, the ship can not longer so large an angle to hit the banks - so it gets a little safer. The ship was not too long - it was too short. :-DD
