REACTION ENGINES, ONE of the brightest prospects in European space plane technology, had big news this week.
BAE Systems, the globetrotting defence and aeronautics giant, just bought 20% of the firm, and it’s making a major investment in Reaction Engines’ most promising ideas.
The big idea is an unpiloted and reusable hypersonic space plane. It’s called SABRE. Here’s how Reaction Engines describes it:
A new aerospace engine class that combines both jet and rocket technologies with the potential to revolutionise hypersonic flight and the economics of space access…
This new class of aerospace engine is designed to enable aircraft to operate from standstill on the runway to speeds of over five times the speed of sound in the atmosphere.
SABRE can then transition to a rocket mode of operation, allowing spaceflight at speeds up to orbital velocity, equivalent to 25 times the speed of sound.
Reaction Engines’ technology has undergone extensive independent technical assessments which have confirmed its viability and potential vehicle applications.
According to a press release from the Oxfordshire-based company, BAE has bought 20% of the company and invested £20.6 million ($31.79 million). Reaction Engines is expecting another £60 million ($92.60 million) in the form of a government grant.
Here’s what Reaction Engines expects the plane to look like:

Here’s what Reaction Engines says it is getting from BAE:
The working partnership will draw on BAE Systems’ extensive aerospace technology development and project management expertise and will provide Reaction Engines with access to critical industrial, technical and capital resources to progress towards the demonstration of a ground based engine — a key milestone in the development of the technology.

It was much more than a mistake though. They made a deliberate decision to book revenue from suppliers at a particular stage. Even if that didn’t break the rules, it’s the sort of aggressive policy that rarely ends well.
And the bigger story is that more than a fifth (possibly even more) of Tesco’s profit comes from payments from *suppliers*. That is only sustainable while you dominate the consumer end. Real trouble ahead.
Me to the staff are rude, unhelpful, surly and they do not smile, continue doing what they are doing when a que is building up and then have an attitude when they have to serve you. I stopped shopping in Tesco a long time ago and would never go back
Tesco is sh*t. Their meat is crap, I won’t say the staff are rude, I just don’t think they care. Their prices are absolute nonsense, 30 quid gets you a barely half full bag of shopping – ridiculous!
If you’re not a major fan of lidl or aldi, and sick of Tesco using your hard earned golds to fill their accounting holes then Dunnes is your man!
In fairness Tesco prices are very high, and people just cant afford to shop there anymore, i only go to Tesco for washing powder, and if they have a deal on something other than that wouldn’t go near the place.
The person who stands up and says, “This is stupid,” either is asked to `behave’ or, worse,
is greeted with a cheerful “Yes, we know! Isn’t it terrific!” FZ
