The plane enthusiasts thread

[Illaveago]

I saw the new Boeing 737 Poseidon maritime patrol aeroplane at Bournemouth Airshow doing some low fly bys and wasn't impressed! It has a pathetically small bomb bay. It looks like the Boeing marketing people are trying to shift some old airframes .

It's not just the contents of the bomb bay that the bad guys are going to worry about:

I pride myself on being a nerdly plane nerd, and I love this thread. Some great pics, and I look forward to more!

Ta , I’ve got some yet , I’ll put them up later today ,

Can you explain BIL7777?

Sat off the north coast of Ireland at 62,500 feet for the last three months.

The most likely explanation is that those signals are entirely spurious.

Looking at the data on the flight trackers, we are asked to believe that two stationary* objects occupy exactly the same position in the sky, one precisely 1,000 feet above the other. If, as suggested by some, they are balloons, how do they stop something that's on the end of 12 miles of wire from drifting around with changes in the wind?

* the two "objects" each actually send two alternating positions which are about 9 feet apart in a NW-SE direction, same every day:

(substitute any other date, and the "track" will be exactly the same)

Trust me, they aren't real.

First appeared on radar at 62,000 feet in early June, heading North from the Mayo coast.

I always check on this every time I log on !

Don't you get bored when you find nothing has changed since yesterday ?

Out of interest, when you say "log on", what tracker are you using ?

Why do the Danes claim something that isn't real.

It's not just the contents of the bomb bay that the bad guys are going to worry about:

Harpoon anti ship missile. Eees nice! Blue band = dummy round. I'm not sure what the single red band means on the inboard round.

What you are seeing is almost certainly the weather data that has been transmitted from Billund in Denmark (IATA airport code BLL) since April of this year, using the same frequency as airborne ADS-B/UAT.

Someone, somewhere who feeds the flight trackers is receiving that data (i.e. is within range of Billund) and it's being misinterpreted by the trackers (not unreasonably) as if it was an aircraft transmission. Presumably there are bits in the data that change only slightly from transmission to transmission, and they are being decoded by the trackers as spurious position and altitude values.

Understand if hadn't moved since first "sighted", but first sight was off the North Mayo coast. Leading many to assume it was a missile.

Following the link, gives a 300 nautical mile limit.

That's correct - whoever is feeding the data to the flight trackers must be within 300 nm of Billund in order to be able to pick up the transmissions.

Incidentally the spuriously-generated position of those "objects", which just happens to be off the coast of Ireland, is at precisely the same latitude as Billund, and their longitude is exactly as far west of Greenwich as Billund is east.

And if you head due South, where do you make landfall?
