I was in Lincoln last week and surprised to see the “Red Arrows” several times in formation over the city centre followed by what looked like a Wellington or Lancaster.
Talking to one of the locals, they are so used to seeing these aircraft because of the numerous RAF airfields in the area, they don’t even bother to look.up.
Red Bull had their DC6, Mitchell and Lightning over for the show.
It could also have been the Blenheim.
