Apparently not, Air Defence radars do not rely on Secondary Radar as they don't expect a "hostile" to be nice and squawk conveniently. All Primary Radar based with computer aided tracking
Fair enough. I suppose once a friend = always a friend was a reasonable assumption to make - until 9/11, at any rate.
I wonder how closely you need to "shadow" a friendly aircraft before your return disappears?
Probably within 500m, positioning is then critical to avoid wake turbulence... slightly above and behind is probably most comfortable/easiest as the 'lead' aircraft is then lit from above by moonlight, so easier to spot.
Interesting theory here: http://keithledgerwood.tumblr.com/post/79838944823/did-malaysian-airlines-370-disappear-using-sia68-sq68
On the face of it, this sounds feasible, however, it does rely on the SIA flight arriving at the required 'rendezvous' point at the right time. Such information could have been established by listening out on an appropriate frequency, and if that is a particularly busy route, it may have been possible to take a chance, and 'latch on' to any appropriate A/C.
Off the top of my head, there are at least six aircraft from that part of the world heading to Heathrow alone at that time of day, probably a further two flights each to Frankfurt, Paris, Zurich, Amsterdam and Madrid/Lisbon...
Al can you give us an inventory of what was in the planes hold? (other than passenger suitcases). It might just have been carrying something of huge value.
If not then I am back with Part One -the plane has been stolen and landed somewhere like Somalia . Part Two - it is going to be used in a terrorist attack. That would explain why no group has yet claimed responsibility. It certainly is a well orchestrated plan.
It's possible that it was carrying high value goods, but beyond luggage and post, the odd painting/ming vase doesn't warrant the lengths that have obviously been taken...
It was almost certainly landed in Pakistan, as sections of the government there are known Al Qaeda sympathisers.
From there, central and northern Africa are obvious hidey holes, with extremist tendencies. Although a project of that nature would be best kept close to home.
With a fresh electronic identity, it could be flown anywhere using legitimate flight plans, so once it moves, it will be via somewhere, possibly Sudan or Libya to refuel and then anywhere...
UN building in New York, World Cup opening ceremony, The Hague, Lundun and The White House/Pentagon are all pretty obvious targets
Making the plane disappear is the easy bit... will it be the only one? The only way to
prevent it from moving eliminate the threat is to ground every single aircraft between Europe and the Far East, actually now it's past 10days, globally.
The threat isn't the disappearance of one aircraft, it's what happens next...
As I asked earlier, that's the question that noone dare ask...
