See; the XC120 Packplane - http://en.wikipedia.org/wiki/F.... Though the fact it didn't work in 1950, doesn't mean it can't work now. I keep an open mind.
However, the idea of sticking the pod on a railway waggon is a complete non-starter - I'm sure a pod that meets railway crash-resistance standards would be stupidly heavy for aviation use.
Although the introduction of locking cockpit doors had the effect of defeating one security threat, but also introducing a brand new one.
One thing he got wrong, the tank crewman at 7:14 isn't the driver, its somebody starting the engine. Engines of the period had crank-starts. I don't know why British WW1 tanks had the crank handles on the inside, but I'd guess it was because the engines constantly broke down and had to be restarted, and you'd get shot if you had to go outside to do that.
In this picture https://upload.wikimedia.org/w... - you can just about see the crank handle, on the left of the window.
This is what the actual driving position of one of the things looks like.
>It's well known that corners were cut when building the titanic - particularly with the rivets which metallurgical analysis confirmed were cheaply made and weak due to large amounts of iron slag in the composition of the metal. The crew was operating at night in a stretch of water that was well known to contain icebergs and had claimed a recorded 20 ships already. Essentially they were operating blind. Lookouts failed to spot it, either due to environmental conditions, pure laziness, or overconfidence in the ship design - we may never really know.
The Titanic's sister ship, the Olympic differed in detail, but was essentially a clone. The Olympic served on the North Atlantic run for two decades and was only retired in 1935. She gained the nickname "Old Reliable". - Picture of the two together
This suggests that whatever people now say about the design, construction, or the metallurgy of the iron, by the standards of the time, the fundamental design of Titanic was sound and the construction was perfectly fine. She was sunk by a crap-load of bad luck and four compartments being breached - a set of circumstances the designers hadn't envisaged.
BTW - "A set of circumstances the designers hadn't envisaged" seems to me what often happens when an airliner crashes. So we really shouldn't be feeling too superior about this.
