Very tragic result, which I fear the AAIB will find several areas of concern. Unless Leonardo have a different CAT A confined area profile from the AW139, then he was in between that profile and a back-up profile(something that would not have worked going out of that stadium.
Stadium top obstacles? Wind direction? Why the gear up before VTOSS? At a crucial stage of flight the Pilot selected gear up(collective hand used) If he didn’t select the gear up, then a non-rated ‘passenger’ in the left seat, reach across the center console to make the selection? Swiss cheese model.... plus bad luck. Damned bad luck.
