I had a fright yesterday and it was a seriously close one!
Two of us in a Robin 200 (myself and a VERY experienced instructor) near Clacton. We were in the process of doing a clearing turn prior to some stalls when a Cessna passed directly below at I would estimate no more than 50' !!! Frightened the Cr@p out of me! Especially as neither of us saw it until it passed underneath and would have had no time to react. Worse still, we were both looking extra hard for other aircraft as part of the training checks!
I had one near miss years ago and now this one. Both in areas where flying schools tend to do excersises ... Must be a cautionary note in that surely?
