Or it could show a piece of fabricated video. Even in 1955 they produced better quality imagery of something no one was expecting to happen.

It is a film sequence taken from a lot of camera stills, you will find photographers take a burst of shots when an aircraft is manoeuvring, then pick the choice images, I do and my 1DX can shoot bursts up to 14 frames a second, this chap obviously got lucky as the aircraft completed a roll or two and the sequence has simply been tacked together to form a video. Without joining them together and showing them as a whole, the individual shots could be interperated as simply the wing overs viewed from various sides.

As for fabrication, trust me, it is very difficult to alter the shot meta data and compile a lot of shots to make up a sequence like this, lighting, sun angle, aircraft pitch, roll, size etc all come into play.

NutLoose, I have to admit the control inputs displayed at 00.13 in the video do look as though they tell a story, but as there is no external reference other than sunshine and shadows can anyone definitely say what occurred as the video is not real time but as you state, picture stills joined together.

Well, if the images are supplied upon request to the CAA then they can read the images individually, I will give you an example.

one from the good photo thread, hope they do not mind

http://www.pprune.org/jet-blast/3511...ography-5.html

Using this site to read the metadata

http://regex.info/exif.cgi

you just need to run the picture location through that.

Nikon D60Lens:55-200mm f/4-5.6
Shot at 200 mm
Exposure:Not Defined, 1/800 sec, f/5.6, ISO 200
Flash:noneFocus:AF-A, Center
AF Area Mode: Dynamic Area (closest subject)
Date:December 29, 2008 2:25:03PM (timezone not specified)
(6 years, 10 months, 14 days, 14 hours, 12 minutes, 23 seconds ago, assuming image timezone of US Pacific)

now you can hide that data, but if you were supplying it to them, why would you?

Someone has written a letter to the newspaper which first broke the story.

Grantham Journal letter: Nothing unusual about the Vulcan - Grantham Journal

Whilst this chap seemingly courted publicity with his photo allegations I have yet to find a single copy of any of the original stills online. All we have is his crude conversion to a youtube clip….

Was the Vulcan ever cleared for a LABS manoeuvre, if that's a question anyone is allowed to answer?
Ok as a none pilot I'll field this one, they were certainly cleared to do it in public back in the late 1950s and very early 1960s, at Farnborough. That is to say Vulcan, Victor and Valiant were all recorded performing the LABs manoeuvre.

Thanks, I've seen a YouTube video of the Vulcan's attempt....

I surmise the alleged roll is pure BS spread by a internet gnome with far too much imagination and time on his hands, and extremely poor photoshop skills.

While we are going round in circles, right/wrong, safe/unsafe, rules etc, what of the facts?

Is there an investigation? Have the pictures been requested? Have they been offered? Have they been handed to CAA?

Good points PN. This really has become a storm in a teacup IMHO.

Wander00 16th Nov 2015 10:49

PN/Goudie - I am with you both - there are more important things - storm in a small coffee cup!

Pontius Navigator 16th Nov 2015 16:59

I am not aware of any clearance for LABS, B47 yes, Vulcan no.

We had 3 relevant attacks, 2D, a climb to 27,000 feet for level release of Red Beard and airburst, 2E, a climb to level at 11,000 feet for a Yellow Sun ground burst and a 2H, a climb through 10,500 feet with release at angles between 12 and 15 degrees depending on Mark, engine fit and weapon.

Yellow Sun had a non-aerodynamic shape and would have been unsuitable. Red Beard could be delivered using Labs on Canberra, Buccanner and Scimitar.

Latest rumour has them taking over the classic flight aircraft from Coventry, they are also teaming up with the lot working to put a mossie in the UK skies.

Pontius Navigator 16th Nov 2015 17:37

Will it be cleared for barrel rolls?

Treble one 16th Nov 2015 17:52

PN
 
Many thanks , as ever, for the information.


The reason I asked was I watched a documentary about Cuba, and it was mentioned that the 'escape manoeuvre' to get the Vulcan away from the blast after dropping the weapon (YS presumably) was 'aerobatic'.

When will the pleading for cash start......................

Well indeed. But they've had all they're getting from me. I've cancelled my monthly donation and split it so that half will go to 655 MaPS and the other half to FNHT.

Stitchbitch 18th Nov 2015 05:56

FNHT? A worthy cause. Mosquito, there's one in NZ that will eventually go to BHHH and join their fleet once restored. As for Vulcan rolls, let's hope this gets cleared up soon, for all involved.
