Struggling to start the swine currently.
Not a drama...yet. It did the same in Newquay when we tried to start it, but we hadn't shipped equipment quite as far. I was surprised they didn't try to start it over here before leaving.
Same thing crossed my mind too but I'm sure they know what they're doing. Since it's not run for years do you know if any parts needed to be rebuilt due to worn/aged seals etc?

I know the engines are all short on FLIGHT hours, but as they will have been properly stored at RR that should not be an issue & they will hopefully have been checked by RR, it is to my knowledge the Newquay engine so has run it the car previously, could just need to clear it's throat.

@ Call me Legend.
Re - Thrust 2. My great uncle was Gordon Flux, who took me along to see it when it was being built, without any bodywork.
Having seen Bloodhound at Avonmouth, I know which one I'd feel safer being in!
John Ackroyd was the designer. His book is interesting - particularly the hot air ballooning!

They deleted their tweet of them stating they were having issues starting the engine, so guessing not. That's really not how to do social media...

I thought I saw that post and then couldn’t find it again.

But then there’s a post on Twitter of tracks on the track so to speak.

So run or no run?

According to Facebook at 20:11 today.

High Speed Testing: Update
Today the Bloodhound LSR team took the car out on to the Hakskeenpan for the first time. They made two unsuccessful attempts to start the EJ200 jet engine, but there was no ignition. After reviewing the data the engineers discovered it was an issue with a fuel sensor calibration which stopped a pump from sending fuel to the engine. After recalibrating the sensor we made a few more attempts. On the final run the fuel pump worked perfectly and the jet received fuel and ignited! This time the inhibitor fluid that the jet engine was filled with for storage was burned off (that’s the smoke you see in the photo). However, the start up cycle took four seconds longer than the 60 second start process and automatically shut down - as it’s designed to. We’re confident next time out it will run without issue. Nobody said land speed racing would would be plain sailing!

Don't know much about this LSR machine.

But when I saw an article about it, I told a friend, "Watch, it'll have some clever twist to the livery that only they would do." They being Britons.

And, lo, have a look at the vertical stabiliser. It's not, at second glance, what you expect to see -- such is the abstract borrowing from the flag, crucially, with black and white elements / screens.

I'm hearing that the car has indeed started today, no news on speeds.

Maybe you heard it here? The 166 page PH thread with one of the design engineers and one of the current crew in the desert:

What really is the point in having just 16km of track to test it at just 500mph. All cleared by nigh on slave labour no doubt as well.
World record breakers of old never went through all this bs, they built their cars and just ran them up to the max.
Yes, this one is (could be) faster but even so this has been going on for years and they're trying to start a jet engine with inhibitor fluid still in it!
This is easily cleaned out with any type of solvent, even petrol including the combustion/flame cans.
It all smacks of heath Robinson..

I think if you had read about all the work needed to build such a vehicle you would not have written your post......

That's not even slightly true.

Ever since venues moved from beaches to dry lakes, there has always been a lot of track preparation involved, and most attempts have been quite protracted.

If you want some idea of how bad it can get when luck runs against you, read the book 'Bluebird and the Dead Lake'.

There is a specific process for de-inhibiting an engine after long term storage, I'm surprised they a) didn't follow it or b) were unaware of it

Which is crazy to think about as an illegal speed in the UK but chicken feed in this context...
