Longhitter:
I don't think it's scaremongering. The steeper glidepath probably magnifies small errors due to the descent rate, leading to more bits of bent metal. I'd expect LHR/LGW to have more incidents because they have more traffic, but that isn't the perception I get, not that PPRuNe is going to report everything. However, something upsetting LHR traffic is likely to get noted on here somewhere, simply because it affects a lot more people.
