On the 11th July 2025 an Airbus A321F arrived at Shannon airport Ireland from the USA, registered as N995CM ( s/n 1619 ). It was painted white with a maroon tail and had Warsaw Cargo titles ( a new freight airline ).
The nose wheel doors were marked "WCA" - it will shortly become SP-WCA(3). This will be the third use of this registration since 1945.

The original SP-WCA(1) was An-2 s/n 1G105-50, this was registered from August 1969 to May 1977 and was cancelled after an accident.
SP-WCA(2) was PZL 130T Turbo Orlik s/n 1900008 - this was previously SP-PCD. WCA(2) was registered from October 1990 until December 1999 - after a period of storage at PZL Okecie this Orlik was sold to a private owner in the USA and became N450KM and later N552PZ - photo below shows SP-WCA(2) inside the flight test hangar at PZL Okecie.
