A big foreign aircraft was awaited,
the Russian four engine TB-7 (ТБ-7 = Tяжёлый бомбардировщик-7 = heavy bomber-7) with the serial no. 42066. If you look for such a plane you also have to search the designation Pe-8, as in the Soviet Union the aircraft first were named after their intended purpose,
but on 8 September 1942 the Vice-Minister of Aviation Industry Alexander Sergeyevich Yakovlev (Алекса́ндр Серге́евич Я́ковлев) ordered that all planes were to be renamed aftertheabbreviationsoftheirdesigners,
the TB-7 to Pe-8 after Vladimir Mikhailovich Petlyakov (Влади́мир Миха́йлович Петляко́в, Пе-8).
One very unusual characteristic of the plane in RAF Tealing is the presence of red stars on the wing upper surfaces, unique in 1942, probably painted to avoid the risk of misidentification by British and US interceptors.
