This Belgian Air Force SF-260M+ Marchetti (ST-26+, msn10-26) is seen parked on the KB taxitrack during the very wet 2022-Spottersday, wearing its standard high-visibility c/s nowadays. In May 1976, I made my first solo-flight in this same aircraft, although it had a completely different c/s at that time and it had not yet been upgraded to SF-260M+ standard.
