I-SJAQ, the SIAI SF-260 designed by Stellio Frati and built first by AviaMilano, then by Marchetti which had acquired the whole production rights. Note this curious demonstrator take-off with vortex generation by propeller and the already off-ground right main undercarriage leg...no flaps being extended and stabiliser having a slightly negative position.
This was due to the kind of performance done by the Marchetti demonstrator pilot which always searched to quickly acquire a very high speed when at ground and do a vertical climb immediately after rotation.
