Maybe, just maybe the Tutor was aerobating when it collided with the Cirrus -
Hasell checks, couple of manoervres, all ok - coaching and mentoring a cadet who is in his element, pulling up into the loop - BANG.!!!
Million to one accident, and one where i would struggle to aportion any blame... just really, really sad bad luck....
This almost happened to me in the CAP 10 in May but with a C172 as the traffic..
Aerobatics in the most basic form requires intense cockpit and mental management, coupled with good lookout.
But it is incredibly, incredibly difficult to see high performance gliders straight and level coming at you perpendicular when you are looping and rolling above the countryside!
The answer is not to ban AEF flying and stop cadets living the dream
The answer is to have notam'd aerobatic boxes close to the airfields that have these requirements - and yes glider pilots do read notams!!
And / or fit gliders with HISL's top & bottom of fuselage - 90% of close calls with gliders would then probably disappear......!
All IMHO
