What an amazing sight for plane spotters.

This Boeing C-17 military transport aircraft was spotted above West Yorkshire earlier today, although only a few people knew what it was.

The impressive plane flew over Leeds Bradford Airport in the afternoon and was also spotted in the sky above Dewsbury, Rothwell and Otley.

Twitter users posted photos on twitter, saying how impressive it looked against a blue sky.

Leeds Bradford Airport posted a video and commented: "What a sight. Did you spot the #C17 flying over LBA this afternoon? #RAF #avgeek #aviation."
