Respuesta :
The right sentence would be Sitting in our airplane seats, we saw the farmland pass below.
What do you mean by past tense?
Past tense is used in a verb to indicate an event that has been done in the past. It means using the second form of a verb.
The given sentence should be written in a past form as the event of seeing the farmlands have already happened at the time of sitting in the airplane. The 'farmland passed below' is incomplete in itself and it should be written as we saw farmland pass below that means the past form of 'see' which is 'saw' should be used instead of the word 'passed'.
Therefore, 'we saw the farmlands below' would be the correct form of completion of the given sentence.
