SpazSinbad, That's a nice photo, but a few milliseconds too soon. Neither the wheels or the hook have reached the wire, so it really doesn't show what is needed.
I take it the new hook is optimized for trapping the wire rather than minimising damage to the pendant. From what I have read, a flat bottom gives a good trap, but the sharp edge is prone to cutting the wire (or pendant), so a rounded lower edge was normal on most recent carrier aircraft to reduce the likelihood of the hook wearing to a sharp cutting edge .
