I was at Holbeach '88 to '90.
4 x Tonkas from TWCU arrive to do some toss bombing on the far ship target (can't quite remember the number, 8 I think).
Anyway, out of 16 bombs (4X4) 14 "DH"s, ie within the 50 foot circle round the target. Of those 14, 12 hit the ship and 2 just missed so the real thing would have done lots of damage. The 2 outside the circle? Well, one would have taken the bow out and t'other would have had the stern off.
Impressed, I certainly was.
I can imagine a Bucc with Tonka avionics and a well trained crew would have been magnificent.
