# Thread: the plane "arrived" or "has arrived" an hour ago

1. ## the plane "arrived" or "has arrived" an hour ago

1.Unless I'm mistaken , the plane _____ an hour ago.
(A) has been arrived
(B) arrived
(D) has arrived

Why not D?

In my (very) vague memory, my teacher has told us that when describing the arrive or leaving of trains/ships/planes, use simple past instead of past perfect. Is this the reason why the answer should be B?

It's nothing to do with arrivals and departures; it is to do with how we locate the action in time. The following are all correct:

The train has left, so we'll have to catch the next one.
The train left an hour ago.
The train had left by the time John got to the station.

Our train was leaving as we got to the platform.

As 5jj has indicated the tense in your example has nothing to do with arrivals/departures. "Wht not D ?" Because one of the uses of the present perfect is for past actions whose time is not definite and therefor "has arrived" and "an hour ago" are not comatible.

Sorry, should have been "compatible".

Thank you very much for explaining reason why, giving more examples, and correcting my errors! X-)
I completely understand now.

Billmcd, thank you very much, too!
