I'd appreciate it if someone would answer my question concerning the following sentence. Thank you.
Many times, planes would crash after they had already started their flight home, most often from damage and mechanical failure. In an interview, V. C. talks about how he witnessed a plane blow up right in front of him, just before landing. He said “they all dropped the bombs in the Adriatic, you know, before they landed. They had to clean off the field before we could land anyway, because there was plane scattered all over.”
(My emphasis)
How is it right to use plane without an article? How can it be a non-count noun?
