Task: Question Answering
Input (English): Context: This was not your usual sort of failing to get in , this was a series of lurch , bump , slight crash , back up , lurch , repeat and rinse . Yeah .... it was one of those days . Needless to say , I miss my plane , after having sat on the tarmac of the plane in Newark for 45 minutes ... That 's right , human error . I quite literally watched the minute hands on my watch tick down , and tick over . 
Question: What may be the reason for them missing their plane ?
Output (English): They were waiting at the wrong tarmac .
