Nope! 5G eh That aint no tinny rocket in my book do the sums for a typical train of 30 carrages each with 30 000Kg and an engine of 150 000 (Not a small one) Kg hooning along at 60Kph. Total curb mass of 1,050,000 Kg slightly more than a moonshot (Not much in fact if I recall from my jet days 600 000 for a Saturn 2, may be wrong some one will know). An ICBM is a solif fuel rocket and quite large to lift a payload of 5000Kg, OK so it goes a bit faster, just attempting to get a grip on size. Also I think that it is a bit hard to control the burn of a soild fuel rocket, all or nothing, so a nice jolty shock. Well WAY OT but fun! PS Note that the name is not 400 characters long. I must practice my english as much as possible, so sorry for it I seem to ramble on and on and on. I think that I have mastered 10 000 of the 830 000 words including the double meanings like:- Engaged Occupided Bar The difference between Bad and Not Good The way that NOT does not always negate a sentance and how it can be loaced at the end eg. Why not, When not, If not, Because not The way the so many words sound the same but as spelt differntly:- Not, Knot. Which witch is which. Weather, whether. There, thier. Its' it's And that great one of when letters for differnt sounds than you would think:- gh == f etc.. Wow, tough!
