Most sources I can find indicate that Mosquito HR573 was lost in Apr45.
For example,
http://www.airhistory.org.uk/dh/_DH9...odn%20list.txt
(which BTW seems to be a copy of the info in the Air Britain serials books)
says "Lost 4.4.45 NFD"
However, Jeff Jefford's opus "The Flying Camels" notes this aircraft, coded OB-K, as being involved in the sqn's last operational mission of World War II, on 12 May 45 (Fig 11.3, page 301). In the list of serials at the end of the book (page 506) it says the aircraft served with the sqn "until 20 Jul 45 at least"
Can anyone please clarify the situation?
