Costa Rica landing in the news, concerns to be taken seriously?
Please don't link to media articles in the general press, but especially not the Daily Mail who generally don't worry too much about facts and have no-one on staff who has a clue about aviation (&quot;activate their tyres in time&quot;, &quot;With its landing gear ejected, the plane comes perilously close to hitting ground level too early&quot;).
Just look at the rhetoric in the wording of the article body.  It ticks all the boxes:

...within a few feet of terrified drivers...
...Shocked passengers on board...
...eye-catching video...

The Daily Mail tries to get at least one of these a month as clickbait and for comments.
Some critical thinking.

...grazed perimeter fence...

No evidence presented.

...why so many photos...

Because the road is right at the end of the runway and spotters gather there to take such photos.

...passengers shocked...

No evidence presented and most passengers are the worst possible judges of a good approach or not. How would they know?

...how low was it at the threshold?...

No evidence presented.

...airport authorities insist it was a normal and 'controlled landing'...

What evidence is there that it was not?
SJO is known for its tricky and low approaches.  Nothing to see here.
