The point is there is no way, or at least it is very very highly improbable for a ground station like a cellphone to pick up direct transmissions from an aircraft that can be used to identify that aircraft. The transmissions to satellites will only be in the form of a very highly focused upwards pointing energy beam that is likely to be irregularly available - particularly in the landing and take off phases. That was my theory anyway....but " Plane Finder AR blends the data from our Plane Finder virtual radar apps with the Augmented Reality capabilities of the iPhone to show you what is flying overhead. The app is fun to use and is very dynamic. It will work in all areas for which we have coverage. Please check our web map at www.planefinder.net or ask a question via my.pinkfroot.com to make sure we cover your area. We are adding feeds all of the time so it’s always worth checking back in regularly. Plane Finder AR works by picking up ADS-B plane feeds used by all commercial planes to transmit their name, position, destination and lots more." The Iphone is not directly using an ADS-B plane feed. Those have to be obtained by the application provider and provided to the internet. Even so I agree the satellite tech is way ahead of what I was thinking of when I replied. However ADS-B is not going to be mandatory for all aircraft in Europe. "European mandate for ADS-B OUT requires 1090ES ADS-B Out with a Diversity Mode-S transponder by 1/8/15 for new aircraft and 12/7/17 for retrofits, and only applies to aircraft >12,500lbs or max cruise >250kts TAS."

Those of us who thought they would not succeed should resist the temptation to say "I told you so" I couldn't even attempt what they were trying to do. It must be a very sad time for all on board. Our stop at Beechey Island was tinged with sadness, not only because of the tragic events of all those years ago, but also by the decision to abandon our attempt to transit the Northwest Passage this summer. With the ice situation showing little improvement, even if a late transit may become possible, we could face the prospect of being unable to reach the Pacific before the seas started to ice up again. In such an eventuality the only solution would be to overwinter somewhere in Arctic Canada or Alaska, something that I was not prepared to do. It was therefore decided to turn around and sail back to Europe while the weather conditions in the Northern Atlantic are still favourable for our 2700 miles passage home. The first response to my decision came from my son Ivan. I quote his words here, as they reflect exactly my own feelings: “Seeing as there seems to be a 50/50 chance that the Northwest Passage won’t open this year, it may be for the best to turn back. This is something my cycling has taught me about being audacious: it’s better to have tried and possibly failed than not to try at all!” It seems however they had a very good chance of getting into Resolute and then down to Bellot Strait. These are historic places worth going to having come so far. Even Gjoa Haven is a possibility given their constraints of not wanting to overwinter in the Arctic. They are failing before trying

tell people to invest in the smart phone app that lets you point your phone at an aircraft and it will display its Callsign, departure point and destination. Aircraft now carry a unique ID which is broadcast around twice a second this is going to be mandatory for all including military aircraft, or they are not allowed into the airspace. Nowadays aircraft cannot just fly around they all have to be 'known' unless they are small puddle jumpers and that is not the type that the chemtrail tin hats are for. I am fairly confidant those cell phone applications are only using the information that ATC believes is correct or would want you to believe is correct. Aircraft are not currently able to transmit their identification to ATC. All they do is transmit a code given to them by ATC which they only get when they contact ATC. Currently military and civilian systems are not coordinated. Civilian systems are using technology developed around the time of WW2. At a guess when you point your phone at the aircraft the picture you see on the phone via your camera is the phone applications guess via your position and the position of aircraft that is available on the internet. So if so, it works fine for two aircraft flying in different directions but not very well for two aircraft travelling in a similar direction

In fact in 2013 it appears at least 3 sailing boats made it thru the north west passage westwards........ traversayiii.blogspot.fi/2013/09/saved-from-defeat.htmlwww.sailblogs.com/member/libellule/?xjMsgID=319894But.... They only made it thru Bellot strait with icebreaker assistance traversayiii.blogspot.fi/2013/08/setbacks-and-triumph.html"The Swiss catamaran LIBELULLE joined us in our early morning vigil. In the end, perhaps 50 meters of ice separated us from freedom. In calm waters, we would have tried to push through but in the swirling tidal currents, it would have been very dodgy. But there was a trump card! The evening before we had discovered that the Canadian Coast Guard Icebreaker HENRY LARSEN, named for the RCMP officer who skippered the first return Northwest Passage, would be escorting a cruise liner and a super yacht through at this precise time. After his primary duty was done, HENRY LARSEN came back and cut a short path for three tiny sailboats. It closed almost as soon as he cut it but all three of us managed to scoot through! ----- At 23/08/2013 18:40 (utc) our position was 71°40.34'N 096°35.77'W "

Today there is an unusually clear satellite view of the large part of the North West passage that is choked with ice between Bellot strait and King william island. For the time being a way thru is looking totally hopeless. 1.usa.gov/1q9FZRBThe same date last year it looked far better 1.usa.gov/1q9FU02 Last year by August 22nd it was easy travelling to almost Bellot Strait. 1.usa.gov/1q9FI13

I couldn't get your link to load Andrew. The Canadian ice service shows a very small area of ice in Hudson Bay. It is in the north west corner. Cryosphere shows ice in the south, which I know to be a false echo. Canadian ice service Southern chart shows ice in south west part. If you exclude St James bay from the picture the ice is clearly in the south west of Hudson Bay. It is only middle of August. Churchill break up typically happens mid July although it will likely be earlier in recent years. I fixed the modus link Modis satellite view of all of Arctic Play around with different dates to get a feel of what is ice and what is cloud

Modis is showing a small amount of ice in Southern Hudson bay, Cryosphere is graphing Hudson bay ice as being below normal, and ice on the Russian side is particularly absent. Modis satellite view of all of Arctic Put recent dates in at the bottom to confirm what you see is ice - its quite easy if you compare earlier pictures with the more recent ones.

Empiricus is already at Gjoa Haven (after over wintering at Cambridge Bay), so that position page I linked to is many days out of date. Latest news and positions here: share.delorme.com/empiricusembarks

This boat has a reasonable chance of making the passage. The boat is a converted French Navy tug boat. All they need is some more melting and a wind shift which should be possible before the refreeze lemanguier.typepad.fr/

This link will provide the location of all of the small boats trying to get thru the north west passage from the West or the East. www.thenorthwestpassage.info/If you tick a boat in the box on the right you will see a marker appear somewhere on the route. 15 are marked as Sailing Vessels, 1 row boat and one kayaker either in the passage, waiting to get in it or enroute The same person providing that information is making some interesting comments about the lack of preparation and experience of some of the boaties. northwestpassage2014.blogspot.fi/2014/08/grocery-prices-in-arctic-bottled-water.htmlNot all of the boats look like an ordinary sailing boat: French boat Le Manquier which overwintered at Cambridge bay and going East This couple seem determined to have an adventurous life: empiricusembarks.wordpress.com/author/empiricusembarks/

Made it to Arctic bay in time for Saturday drinks and have reported no ice blog.mailasail.com/suilven/217They will probably want to make it into Resolute for next Saturday.

It is an interesting thought that having a kayak to get a GPS compass bearing could be a life saver in the Arctic

It is only first of August. That ice will look very different by mid august. That said though those keeled boats have no ability whatsoever to pass thru even small amounts of lightly compressed ice so its no place to be taking a 14 year old boy if its not plain sailing.
