The round gear leg C210's have been around for 44 years.
I think you should cut the pilot a bit of slack RT, I been flying C210 for 39 of those 44 years and have never before heard your revelation!
Also have plenty of time in C172RG, 177RG and 182RG - pretty much the same gear system as I understand it.
I have had a few gear issues with them - but never bent one!
I am curious, however, as to why flicking the electrical pump on just prior to landing will achieve anymore than pumping the emergency handle?
And yes - I would have put it on the bitumen, but I am not going to point the bone at the PIC!
Its only a frigging aeroplane - it can be fixed or written off!
Everyone walked away - nice work, I say!
