About pics..
By the looks of it, skip bombing techniques were mostly used by B25 crew and B17. I have a cr*pload of different publications about WWII birds... I have yet to find any pic of a B17 skipbombing..but found quite a few B25's.
Take note that the "2nd plane" is a shadow... taken in Bismarck sea
Take note of altitude..bay of Hong Kong
Take not of altitude.. I would say considering the B25 has a wingspan of 20 m, this one is I would say 50-60m
Note thouh the text.. just because a B25 is low doesn't mean he is skipbombing. Front guns were quite heavy and could do a lot of damage.. and when u are strafing u need to go low
