Having trouble identifying subordinate clauses in the following sentences.

1. The airplane that we saw can land in only a few airports in this country.

I think for this sentence the subordinate clause would be "that we saw."

2. The coin that I purchased is an old French crown.

I think the subordinate clause for this one would be "that I purchased."

3. Those who would control others must first control themselves.

I think the subordinate clause for this one would be "those who would control others."

1 and 2 are right.

3. You have one word that does not belong in that clause.
