Crowds watching the VJ Day celebrations in London were entertained by a fly-past of military aircraft, but technical issues meant only three of the five expected planes took part.
A Dakota, Hurricane and current RAF Typhoon fighter jet flew over the capital.
But the well-loved Spitfire and the Royal Navy's Swordfish, the world's oldest surviving bi-plane, were absent from the spectacle.
A spokeswoman from the ministry of defence said: "The Swordfish was unable to take part in today's Victory over Japan Day anniversary celebrations due to a last minute minor technical issue, which prevented the aircraft from flying."
Veterans of World War Two have been taking part in events to mark the 70th anniversary of VJ Day, Japan's surrender and the end of the war.
The royals joined the prime minister at a special commemoration service as events across the country marked 70 years since WW2's end.
People have been encouraged to attend VJ Day events on Saturday amid reported terror threats in London.
