Depends on how you define "correct". Will you hear it in a normal dialogue? I suppose so, the 'did' can be dropped if properly implied just like I dropped the initial 'that' in the first sentence of this reply even though it is the subject of the sentence. But you won't find it as an acceptable grammatical variant in any grammar book.
