One of my favourite aircraft has always been the Douglas A-4 Skyhawk, an aircraft which would seem impossible in the modern defence industry in having achieved its specification without turning into a monumental bit of over-priced flying bloatware and which was a very pretty little jet. And the best of the series in some ways were the re-engineered A-4SU Super Skyhawks of the Republic of Singapore Air Force (RSAF), the Argentine A-4AR Fightinghawk has a better avionics fit but the A-4SU was re-engined with GE F-404 turbofans with a big boost in thrust. And they had the unique TA-4SU trainers with a double hood arrangement rather than the more normal elongated canopy. I'd wanted to visit the air force museum for a long time but it was closed for COVID, it has re-opened however and is well worth a visit. Located next to Paya Lebar air force base it is easily accessible via public transport and entry is free. Here are a few pictures of Skyhawks, not good pictures but great aircraft.
