Recall doing a RAS (Ammo) in the South West Approaches one Summers evening. Then, unknown to all, a Concorde decided to do its accel out into the Atlantic heading off to the States..........

That is NOT what you want to hear during a RAS (Ammo)!!!!!!! If the Concorde crew could have seen the looks on our faces bobbing about on our "war canoe" 50,000+ ft below them.......... :ok:

It was loud enough here. Windows duly rattled. But we are getting used to them - second one this year.

Are those ripples in the paintwork down to the shockwave?

Non Linear Gear 12th Jan 2021 18:26

Question is, What was it doing flying into UK airspace without a known flight plan or communications with ATC? I hope the owners get billed the cost of the QRA shout. Travel into this country is essential work only, not leisure. If it is not for business reasons inside the government restrictions.

Rt Hon Jim Hacker MP 12th Jan 2021 19:34

That is one shocking paint scheme. Good to see the Brits intercepting the Germans again.

They will be billed according to a pilot colleague as one day we were flying a fixed wing aeromedical flight from Europe to the UK, he called me up to the front and said a well known airline had an aircraft with two Typhoons sat off their wings some miles ahead and it was going to cost the airline a lot of money unless it was a system failure. Knowing the airline it was probably the pilots who were going to be paying and I suspect a short sharp interview with the CAA.

Caboclo 12th Jan 2021 22:15

I rather like the paint scheme. I wonder if I should apply for the newly opened position?

Apparently mocking journalistic standards today is too easy to even bother with anymore.

Hope the passengers, if no essential travel pay for it. They paid the bucks and likely told the pilots so. If not essential, they should get a flea in the ear too.

Nothing unusual here. In 1940 they came into UK airspace without lodging a flight plan or checking in with ATC!

The aircraft would have been on an IFR Flight Plan and would have been talking to ATC. From the info released so far it looks like an equipment problem (or finger trouble) leading to a prolonged loss of communication. If ATC canít get hold of the crew using all means then an intercept in these circumstances is standard procedure.

Chris Kebab 13th Jan 2021 09:16

If it was a box problem it was fixed pretty sharpish. It was on the ground at Stansted less than 90 mins, did a short hop over to Birmingham for a hour (presumably to pick up the original intended pax) and then legged it directly to Barbados! Nice for some...

Do we have a credible source for "no known flight plan? It may be in one of the MSM links upthread and I've missed it but all I've read points to this being a loss of comms... as LeftBlank says " it looks like an equipment problem (or finger trouble) leading to a prolonged loss of communication."

Another example of 'confused' journalism. Re the Daily Mail story - Learjet? or Global Express?.

Imagegear 13th Jan 2021 10:21

From what I read earlier, the handoff from Belgium (Eurocontrol) disappeared into the ether as they crossed the North Sea.


The plane was apparently a private aircraft from Nuremberg, Germany, according to flight trackers.

The RAF has since released a statement, saying: ďQRA Typhoon aircraft were launched this afternoon from RAF Coningsby to intercept a civilian aircraft that had lost communications; subsequently, communications were re-established, the aircraft was intercepted and safely escorted to Stansted Airport.

Null Orifice, I think you'll find the type was a Garbled ExpressJet and they have an inclusive extraview with David Learjet of Fright International...

Didn't change squawk code then. Cheers, I thought it was totally unannouced. Of course any break in comms is a shout. 9/11 taught everyone that.

Hirer to interceptors: "Do you know who I am?"

Non Linear Gear 13th Jan 2021 18:26

I hope the hirer that flew out of the UK on the aircraft was actually allowed to do so by the current coronavirus travel restrictions. If whom were, then that is fine. If not they should pay for the QRA shout. If they can afford to rent a Global Express, they can afford to.

Almost as cool as the previous owners two Spitfires, although he may have sold up.

I'm sure visiting your tax lawyer in Barbados is essential work...

SLF posting, if I may.

I thought standard procedure was to send two Typhoons up - but only one this time? Any idea why?

Nimmer 15th Jan 2021 14:55

There were 2 typhoons.

Same here - one boom, one contrail, and only one aircraft on the screenshots of the tracking site...

Hah!

I'm not so sure now - the official RAF response referred to aircraft (plural).

Lots of military/security situations have 2 parties operating in cooperation; one that the antagonist (and casual observers) can see, and one that is more covert.

One half of the team (policeman/nightclub-doorman/patrol) makes itself known to the target, attempts to determine their intentions, and seeks to influence their behavior. Because of their observability and proximity, however, they are not necessarily best placed to respond to aggressive or non compliant actions by the perpetrator.

The other half of the team (policeman/ambush party/interceptor) stands back, normally carries a big stick, and prepares to intervene if required. If you've noticed him, he's lost part of his advantage.

Rather than ask why you couldn't see the second Typhoon, perhaps we should be considering why we could see the first? Why would a military aircraft on a live operation employ the tactic of making itself visible on a tracking website and (presumably) on TCAS?

Wild guess: physics?

DuncanDoenitz 16th Jan 2021 14:26

Of course physics. Lots-of-noise physics, contrail physics, FR24 physics and Twitter physics.

All avoided by his buddy (not, I hasten to add, his wingman), who is quietly positioning himself in the target's 6.
