The phrase "...not standing there to the airplanes" is confusing and has no clear meaning.

No meaning in English so we can't come up with the right translation

Does it mean something like the following? : Die Busse auf dem Flughafen parken nicht bei den Flugzeugen. The buses on the airport don't park by the airplanes.

The correct English translation uses the word ‘planes’. No one has used ‘airplane’ since the 1920s

---------- the airport buses don't park by the airplanes . . .

Will someone please retire the airplanes? They must be getting very old

I got "don't park to...which doesn't mean anything

So it's "park" now, not "pull over" or "pull up"? I wish i could report the whole exercise. Please, add some meaning to this.

This is another of those impossible questions unless you happen to guess what the computer wants or you've seen the answer and memorized it. I put, "the buses in the airport don't park at the aeroplanes." There is no difference in meaning. In the airport simply means an area where buses go which would be described as somewhere within the perimeter and the words "at" and "by" are interchangeable in this context. It's the most frustrating aspect of Duolingo but equally, (and I fully accept this), the one most likely to arise.

Now "planes" is no longer accepted for "airplanes"? These shifting standards are bizarre.
