Wellesbourne Vulcan incident
Wellesbourne Vulcan incident
Crew decided to head out by road it seems.
Re: Wellesbourne Vulcan incident
Practice session for a future event at Doncaster???
Anyway, I guess that everyone is safe and sound apart from a needed change of underpants and the Vulcan can be moved back onto terra firma soon.

Re: Wellesbourne Vulcan incident
Thank you, that explains the email I had this afternoon about event cancellation due to 'circumstances beyond our control'.
Unfortunate, but at least nobody injured, could have been much worse by the look of it.

Re: Wellesbourne Vulcan incident
Lots of doom laden comment on social media about such an incident bringing about an end to taxi runs at Wellesbourne. In my mind this is no worse than the ‘Victor to the Sky’ incident some years ago at Bruntingthorpe so hopefully lessons will be learnt then a pragmatic approach will be taken.
Re: Wellesbourne Vulcan incident
From the XM655 Facebook page.
As many of you will have already seen, XM655 suffered a runway excursion earlier today during our trial run for the event which was planned for Sunday 18th. That event has been cancelled, all ticket holders have been informed by email and full refunds have been processed via Eventbrite. As far as we can see, the aircraft is largely undamaged, but in addition to the ongoing recovery work, we also have a lot of inspection work to carry out before we can consider any further live activity.
In an attempt to reduce uninformed speculation, we will explain what happened. After satisfactorily completing low speed steering and braking tests on runway 05/23, the aircraft was taken onto runway 18/36 for a trial high speed run. Due to a malfunction of a piece of equipment in the cockpit, the aircraft remained at full power for approximately two seconds longer than intended. This resulted in excessive speed and less distance in which to stop, and the aircraft passed beyond the end of the runway on to the agricultural area, stopping just before the airfield perimeter. The failed equipment was an air speed indicator which had been tested and found satisfactory six days ago, and which started working normally before the end of the run. The aircraft brakes worked properly but were unable to bring things to a halt within the reduced space available.
We will provide further updates when XM655 has been recovered and we have had chance to assess any damage.

The BBC has a couple of photos: https://www.bbc.com/news/uk-england-cov ... e-62930756
The gear doesn't appear to have suffered a lot, but that's speculation of course.

Re: Wellesbourne Vulcan incident
Ummm, having seen fast taxy runs at this location before I'm not convinced that an ASI is crucial to safe operation? Surely an experienced Pilot in Command knows that keeping the throttle open longer than normal will increase velocity more than normal? It's also a pity these Jets weren't fitted with braking chutes for such situations where excessive speed needs reducing? Clearly if they had only fitted more than one ASI in the cockpit, this may not have happened? I can easily see how the single faulty ASI could be working at the end of the Run, I'm going to risk saying it was reading Zero when its wheels were two foot deep in a field! But that's more speculation of course.

Re: Wellesbourne Vulcan incident
Exactly. They've taxied that aircraft numerous times without incident and so should know exactly where to apply the brakes regardless of the accuracy of cockpit instrumentation.
(Tongue in cheek side note: on the aerial photos you can see there are no tyre marks between leaving the runway until a few metres into the field - does this count as the last fight of a Vulcan for the millisecond it appears to have been airborne? )
Re: Wellesbourne Vulcan incident
I have to agree with this. With only 3500ft odd of runway to play with (426 has nearly double that at SEN, and 558 had nearly treble that at DSA) you'd think one of the cockpit crew as a min, would have a stop watch set for duration of power applied after brake release which you probably don't even need all the fingers of one hand to count before having to chop the throttle levers.....speedbird2639 wrote: ↑Sat 17 Sep 2022, 11:19 amExactly.

Re: Wellesbourne Vulcan incident
The jet is safely back on her hardstanding now. Sounds like they have had a hell of a busy day getting 655 retrieved.

Re: Wellesbourne Vulcan incident
Given how (relatively) short this runway is I very much doubt if a drag chute would have deployed and inflated quickly enough to have been of much help. It is very fortunate indeed that this did not happen a few weeks ago when the field would have been much harder following the drought.Stagger2 wrote: ↑Sat 17 Sep 2022, 9:41 amUmmm, having seen fast taxy runs at this location before I'm not convinced that an ASI is crucial to safe operation?

I don't know the history of how this Vulcan ended up at Wellesbourne or if the runway used to be longer? Given that it is apparently less than half the length of runways at the other venues used for "high speed taxi runs" I do have to wonder if enthusiasm got ahead of proper risk assessments? The simple fact that it has been done without incident before, doesn't in itself mean it was ever a good idea.
I don't know who will investigate this? As there was no intention to fly it may not be the AAIB? However, given that this was on a licensed airfield maybe it does come under their remit?

I found this on YouTube. Rapid chute deployment, standing on the brakes and a lot of crossing and praying , by the looks of that short landing.Thoughtful_Flyer wrote: ↑Sun 18 Sep 2022, 8:18 am[

Re: Wellesbourne Vulcan incident
Looking a Google Maps of Wellesbourne, I think the runway is as long as ever it was.
https://en.wikipedia.org/wiki/Wellesbou ... d_Airfield
According to Wiki the main runway is 3009ft long

Re: Wellesbourne Vulcan incident
Regarding the chute, I imagine that the eventual realisation that the throttle action had been excessive then caused 'brain-freeze'! The video shows no clear evidence of any mitigating actions available being initiated? FIrst action after the "Oh F*** ." would be pop the chute, then full flap, nose-up, wing fences, some brake application leading to pedals on the floor, surely? Anything to increase to increase drag.Thoughtful_Flyer wrote: ↑Sun 18 Sep 2022, 8:18 amGiven how (relatively) short this runway is I very much doubt if a drag chute would have deployed and inflated quickly enough to have been of much help.

The comment about the hard ground was pretty much my initial response to the pictures of the resting position. For weeks previous & this story could've been much worse. The Vulcan crossing the busy B4086 Stratford Rd into the Large field beyond could easily have involved Third Parties. Time to bring in Guy Martin maybe?
Some of the usual sensational journalism is indeed nauseating. A copied passage from Coventry Live here. (copy-pasted in numerous comics)
"Speaking last year, Wing Commander Mike Politt (sic) said: “The aircraft performed fantastically, she’s in great shape, it went flawlessly.
“It’s been five years since the last high-speed taxi, and there were certainly a few people in the café and on the airfield pleased to see her running.
“She may have been brilliant, but operating on a 2,000ft runway might not have been great for my blood pressure!”
The following published data for runway 36 at Wellesbourne is Length = 917m [3008 feet] TORA = 4015 feet] TODA = 4212 feet]. NOT including grass! Make your own judgement.
PS: Video of Vulcan delivery is a good find Ericbee123. Note how quick that chute deploys!

That was of course over 38 years ago. A few factors spring to mind....
Crews then were current on Vulcans
The aircraft was airworthy and could fly as many approaches as necessary for the pilot to be happy
I assume a day was chosen with a significant headwind
The road at the end of the runway was no doubt closed for the landing
And....
The world was far less risk averse!
Had Wellsbourne been considered as the final resting place of XH558 would they even have contemplated landing there in 2015? Somehow, with little over half a mile or runway I rather doubt it!

Wasn't 655 often taxied by the late great Dave Thomas, even to the point of lifting the front wheel off the ground? Surely there would be some written SOP's in place for this event?
If I were the airfield owners, I'd immediately put a stop to any future fast taxiing from 655 given how close that came to the road, and the potential danger to passing traffic. It's just not worth the risk with such a short runway.
Re: Wellesbourne Vulcan incident
Well then it’s perhaps fortunate that you aren’t the airfield owner. Hopefully the real owners will take a pragmatic approach focussed on risk assessment and mitigation while reviewing all of the facts before determining a sensible and practical course of action.
Re: Wellesbourne Vulcan incident
As far as I know XM655 is owned by the airfield...

Re: Wellesbourne Vulcan incident
Problem with this sort of incident is it plays into the hands of the 'Shut down airfields' brigade. The what if a busload of nuns, taking orphans to the seaside had been passing and the plane had hit it people.
Best of luck to the owners in getting another fast taxy scheduled.

Re: Wellesbourne Vulcan incident
I think the risks are pretty apparent for all to see if something goes awry with such a large, heavy and powerful aircraft on such a short runway.106500 wrote: ↑Sun 18 Sep 2022, 3:49 pmWell then it’s perhaps fortunate that you aren’t the airfield owner.

This is just way too close for comfort, and lucky the ground was soft enough for it to basically dig in.

Re: Wellesbourne Vulcan incident
Indeed, that earth was probably just the ideal water content consistency to avoid the Vulcan sinking too deep & stressing the undercarriage to failure, yet not too hard that it didn't retard the velocity at all!
For those wondering, Engineered Material Arresting System (EMAS) is a passive safety system that quickly de-accelerates an aircraft and brings it to a safe stop in case of an overrun. It's usually the lighter grey material right at the very ends of the r/w with full width Yellow arrowheads on it. Also, it's very expensive compared to grass & dirt!
