Yes, and they only managed to do so because (a) they were at cruising altitude when they went into the cloud and (b) they came out of the cloud in time. They basically had to 'bump start' the engines to light them up. Hardly risks to take on this occasion.
Quite right!
Netherlands and Germany?
The German test may have been considered a success because earlier this evening there were several flights that left Frankfurt for destinations on the other side of the Atlantic.
Didn't British Airways also fly an aircraft from London to Cardiff?
That's god news then.
Dave
Air France, 2 German Airlines, Dutch Airline and BA achieved successful test flights.
An issue is the density of ash - below a certain level it may be immaterial.
I suspect the real issue is the move to 2 turbines from 4... #1 - reliability calculations for 2 turbines in place of 4 do not include ash #2 - high altitude may be critical for efficiency with 2 large high bypass turbines
The 767 has a very high rate of climb to get to cruise altitude as quickly as possible. Burning fuel at low altitude may not put it in the drink, but may well require surcharges.
The successful test flights did not say at what altitude they were performed.

Yes dennis - I was underneath it (give or take a couple of hundred miles) when it happened
Which are suddenly going to appear from ... where ?
Likewise the jets, clue - they are currently stranded on the ground
I'm not sure that the 1982 BA 747 Jakarta incident is all that relevant. The BA plane flew through very thick ash that was close to, or part of the plume of ash coming out of an erupting volcano.
Surely the ash concentrations in the UK's airspace now are orders of magnitude less?
I have no knowledge of the risks involved but would have expected that a risk analysis would take proper account of the ash concentration.
Meanwhile, as a photographer I am grateful for the ash-enhanced quality of light, especially in the evening. Those lucky enough to live on western coasts will be treated to some spectacular sunsets!
The high pitched whine you can hear is Frank Whittle spinning in his grave. I think he got a pittance for his efforts . And the then Labour Goverment gave a bunch of RR engines to the Soviet Union. Stalion couldn't believe their stupidity.
If no-one is buying aviation fuel, has the price of domestic heating oil dived like a gliding 747 (or do domestic boilers all use gas-oil/ red diesel)? How much can they store, or do they have to stop refining the crude stuff?
Piloted by Captain Moody, from whom I bought an aircraft once.
It was not a fall, but a deliberate fast descent to a level where oxygen was not needed - one of the crew's oxygen masks was broken - and where engine restart procedures might be expected to work, which they did.

Then cut the flights down to maybe 30% and have no holding patterns.
Comet was a great plane, but it had another fatal flaw.
It required a comprehensive strip down to get to the jet engines.
The Boeing's looked at the thing from a commercial operators perspective, and realised that a cigar tube with wings strapped on and 4 pods dangling underneath was a heck of a site cheaper to fix.
Hence cost pre passenger mile was hugely less.
Didn't there used to be a storage facility at Buncefield?
It's a pretty steep glide angle isn't it? I reckon it would feel close enough to a fall for the passengers
Chris
The glide angle is 15:1, but he had to go down a lot faster than that because of the oxygen mask problem.
Colin Bignell
Most doemstic boilers use kerosene (28 sec) oil. Only older installations use gas oil (aka diesel). The price of crude has dropped but it's still way over priced IMHO at nearly $86/barrel.
Stoping might be tricky as I think the restart is long and expensive. They might be able to scale down refined output. Storeage capacity donno, but if the tanks were on the full side to start with not much...
Who are you replying to? Because you've chopped ALL previous content your posting makes no sense. By all means cut out excess text but please keep the context of the messages.
No, its about one in 20: right up there with a sailplane.
And IIRC there was no 'fast' descent, there was a controlled glide back towards the emergency landing site.
It's the comment from Bruce. I use Thunderbird which uses a tree view to display messages so that you can intuitively and instantly see and understand how all of the messages relate. A consequence of this is that having a load of previous text at the top of a posting becomes annoying. Click on message, scroll down past previous stuff, click on next message and scroll down previous stuff, etc. Be much better if everyone top posted instead. No, I am not trying to troll or be antagonistic, it's just my personal experience.
Bully for you. And what about all the people who don't use Thunderbird?

onward flight
I feel sorry for anyone stranded abroad and I imagine it must be chaos trying to arrange travel. It just shows us how much we are at the mercy of nature regardless of wealth or status.
According to the BBC News, two F16 fighter jets have had their engines damaged because of the ash. Presumably they intentionally flew into the ash? So that pretty much means they won't be resuming commercial flights for another week at least.
