On Course

A contrail momentarily charts the course of a Bombardier CS300 in the skies over East Sussex, seen from the edge of the Parkland at Sheffield Park and Garden as the aircraft emerges from behind a cloud at 13:48 this afternoon.

Identification of the aircraft was carried out by a friend who was with me at the time, who has the requisite app on his mobile phone. He added that the aircraft was not on a commercial flight at the time, so was maybe on a positioning flight or on delivery to a customer.
