30 days at sea



This is a time lapse of a cargo ship traveling from the Red Sea to Hong Kong. Many years ago I sailed much the same waters, but I was on a warship and I remember the trip as being from east to west.

We had left Hong Kong and were in the Gulf of Tonkin when the Yom Kippur War started. The carrier group I was with pulled out and sailed through the Straits of Malacca and headed first to the Gulf of Oman off the Straits of Hormuz, and eventually south to the Gulf of Aden where my ship, and another destroyer, ran a blockade of the Bab el-Mendab Straits into the Red Sea.

It was hotter than hell and the sky was yellow with wind-blown sand. The Indian Ocean was beautiful.

An RC amphibious assualt



I first posted this video in 2013. It is a ferocious storming of a beach by RC amphibious landing craft carrying RC tanks. It seems appropriate, in an odd sort of a way, to run it again on this 75th anniversary of the D-day landings.
