Everytime OHJs are discussed it gets heated. So I am not trying to wind anyone up here. However experiencing two near midairs while correctly carrying out OHJs tends to harden ones opinion. OHJs involve a 'cross wind join' which in my opinion is suicidal at a busy airfield with a mix of low and high performance aircraft. Still at least the wreckage will be confined to the airfield in the vicinity of the upwind numbers.
