The BBMF Lanc has invariably been known as "The City of Lincoln" since she started wearing the Lincoln coat of arms on the right side of her nose in the mid-70s. However, the aircraft's colour scheme is changed on a regular basis with markings chosen to replicate a specific Lanc from WWII.
'Thumper' was the name of DV385, a 617 Sqn Lanc with the tail code KC-A. This was chosen as an appropriate scheme during the Op Chastise 70th anniversary. Previously she wore the markings of EE139 "Phantom of the Ruhr". EE139 served on 2 different sqns during the war (100 Sqn and 550 Sqn) with differing tail codes, so PA474 wore HW-R on the right side and BQ-B on her left.
Being a single word the 'Thumper' name became quite popular. She is invariably known simply as 'The Lanc" on the Flight!
