I'll wear my boots when reading it then.Ouch!![]()

Am I allowed to spoil the book ?![]()
This item is not eligible to be reviewed.
Or perhaps something like this but with laptop replaced with book holder:
Place a pillow on your legs, then the book on top of the pillow.I'm still fighting with that heavy beast of a book to find a vaguely comfortable reading position. I'm fast running out of options.
When I'm deeply engrossed in a book, the rest of the world can seem like it's on the other side of an event horizon.Some say, time slows down measurably in the vicinity of this book due to its mass....
There are things variously described as laptop stands, bed trays etc. (though you can use them on a couch too). I have one like this.I'm still fighting with that heavy beast of a book to find a vaguely comfortable reading position. I'm fast running out of options.
Post one here then.Well, poop. Amazon has decided that, the book being released only on February 12 (in France ?) no review allowed. Drats.
Post one here then.
Just saw this on amazon here in the US,the book being released only on February 12 (in France ?)
This title will be released on April 30, 2025.
The"megaton to orbit per year range" should raise eyebrows. If we are talking about 200 tonnes to LEO per launch, this would be 5,000 launches a year. Considering holidays and shutdowns happen, weare talking about launching day and night, all week, all year, aboutevery 2 hours ! Duration of the effort would have to be 20 years at a minimum, more likely 50 years. Is this even possible? Ok, we will ignore issues of noise and downrange threats, these can be managed by diktat.
You can't move LH2 / LOX infrastructure effective and fast if things go down there.Neat things with runway-to-orbit: you can rapidly move your conops from one airstrip to another if things go down the drain with the neighbourghs. Remember, you have between 100 and 2700 places to go, average.
But we are veering off topic...
But normal airports don't have rocket planes with 180-200dB noise levels taking off from them, alongside the fact that the "aircraft" carries highly energetic fuel and is basically a flying bomb. This is not going to be operating from Heathrow "like Concorde"Neat things with runway-to-orbit: you can rapidly move your conops from one airstrip to another if things go down the drain with the neighbourghs.

Barnes & Noble pushed the release date to April 30, just like AmazonSounds like your big new book HOTOL: Britain's Spaceplane is being well received in the UK so far, Mr Sharp. Congratulations. I am dismayed to find that Amazon has pushed back American availability to late April. We'll see.
Barnes & Noble release date is also Feb. 12 out here in the US:

HOTOL: Britain's Spaceplane|Hardcover
The start of Space Shuttle operations in 1981 marked a new era in spaceflight – with the five orbiters launching numerous satellites, interplanetary probes and the Hubble Space Telescope. But Shuttle was only partially reusable, its external fuel tank being expendable and its solid rocket...www.barnesandnoble.com

Obviously not crossing the North Atlantic at hypersonic speeds.
Delay due to U-Boat sightings?![]()
Well, then it seems that Malta is besieged? Again?
A few years back I asked Richard Varvill about the noise. The issue seemed to surprise him. I mentioned some work done by John Allen on artificial islands being needed and he said they would look into it.But normal airports don't have rocket planes with 180-200dB noise levels taking off from them, alongside the fact that the "aircraft" carries highly energetic fuel and is basically a flying bomb.

Filter out the airports with no population centres nearby and see how many are left. It's going to be far more limited than simply building more pads and barges for Vertical Launch Vertical Landing.
Getting back to Dan's book, the up front trade study in there (pg33) around different launch options is the only one I've seen to favour HTOHL approach. And there's definitely some questionable assumptions in there - the novel HOTOL engine was going to cost only 2% more than Vulcain on Ariane V to develop
And it only took <1 year of HOTOL development for some of the optimistic weights to be removed but also the ability to reach orbit along with it... SSTO is hard.
Interesting, as I remember Richard breifing specifically around the noise issue for an RAeS conference > 10 years ago. This was for Skylon, but its indicative of similar size rocket powered Horizontal Take-Off spaceplanes.A few years back I asked Richard Varvill about the noise. The issue seemed to surprise him.

I think I was suggesting that posting spoilers on here wouldn't be quite so... outright spoilery if they were embodied within a review (on here)!
HOTOL: Britain's Spaceplane was printed by Gutenberg of Malta. To the best of my knowledge, this is the first time there's been a problem of this nature with their work for Tempest. I will pass on Steve's image to the publisher.
