This is one of Oman Air's fleet of four Boeing 787-8s. I've not seen one of these Oman Air aircraft before and its not an airline Ive ever flown on.
It was a cold miserable morning at Heathrow in first light as you can see from the sky.
I really have no idea where my love of transport in general comes from, perhaps it really is just the Aspergers lol ;-)
