Reaction Engines

[Seeker]

I don't know if anyone else has been following the Sabre hypersonic engine from Reaction Engines, a UK company. It's been very quiet and I assumed it had been dropped but it is still being tested:

I tend to keep an eye on events.

Attended a couple of presentations.

Perhaps they should bolt one on to Bloodhound - another project I keep half an eye on and am very glad to see is back up and pushing the speed boundaries.
