Falcons and eagles are day hunters. Drones with IR FPV control can fly at night. Drones using 3G control datalinks are - unlike their predecessors, which used ISM/802.11 - immune to all existing jamming/countermeasures as they use WCDMA. And they can be controlled from anywhere with an Internet connection. |
|
| |
But hey, the government's only had six years warning, how can they be expected to do anything about a problem at such short notice ? |
|
| |
Truesay. Even the French have worked it out for
themselves... |
|
| |
Is it not time for re-purposing of the homing pigeon
with a powerful (radio controlled) magnet on the
head - I know the URL of company with many E-W
magnets. |
|
| |
More a requirement for the classic anti-pigeon technology; the 12-bore shotgun. |
|
| |
Many airports, and public spaces like railway stations, already deploy trained raptors to keep flying vermin like pigeons out of the area. |
|
| |
But it's all too late; the precedent has been set. Anyone with a basic drone gathering dust on top of their wardrobe now knows that they can close a major airport at any time. |
|
| |
Practical solutions are welcome, and saleable, but you might want to start with something a bit less challenging, like working out how to cram that gigantic mushroom cloud back into a nice shiny little Plutonium sphere ... |

//cram that gigantic mushroom cloud back into a nice
shiny little Plutonium sphere ... |
|
| |
I bought some of those mushroom cloud -> Plutonium
sphere tweezers off the Ferengi ebay site... |
|
| |
But it's easier to run time backwards, saves on the
gloves and all that faffing about. |
|
| |
Surely what’s needed is a Jurassic Park style
pterodactyl breeding programme? |
|

Drones can be shot down almost the instant they
appear using exploding proximity rounds. Doing
this sends out the message that it's pointless trying
to shut down an airport by using a drone, as it
won't remain in the sky for any longer than it takes
to track it and shoot it down. It can then be
retrieved for forensic examination. What was done
at Gatwick by the authorities was an abject failure
of monumental proportions as it invites copy-cat
repititions. It's hardly a surprise in the UK where
hopeless numpties are in now in control of just
about everything. |

Buy a size bigger underpants [IT], that way the tinfoil won't shred. Much less chafing, much more comfortable. |
|
| |
Chaff only works for centimetric/millimetric wavelengths, and it's frequency-specific. If the idea is to block control signals, forget it. But mostly, blowing clouds of lightweight airborne metallic debris around on airfields, where there are gas turbine engines with very close tolerances constantly coming and going, falls into the category of Making Things Worse, Not Better. |

They have some good bargains, but it's mostly overpriced tat. However, the earwax treatments they sell are absolutely top notch. |

No, they can't. They fly too low, and there's too little metal in them for the fuze to trigger. |
|
| |
Something like that might be OK for military airfields, but not for an airport. |
|
| |
The smallest AAA round that can mount a prox fuse is a 75mm. Low-level air defense uses small-arms calibres (7.62 and 12.7mm) and autocannon firing point-detonating rounds. Trying to hit a target the size of a dinner plate that's less than 200' AGL means massive collateral damage both inside and outside the perimiter. Systems to control automatic weapons with that degree of accuracy are still in their infancy (changing the nappies is a constant chore). So the solution is still to spray lumps of lead at the target in vast numbers. |
|

It doesn't have to. It only has to be detected to cause vast Embuggerance. |

We disagree. It would have to have been much more coherent and considered to qualify as "abject". |

May we point out that you voted for this ? |
|
| |
It was actually brought down by an Israeli made
system called Drone Dome, as a short search can
reveal. |
|
| |
^ Yes, but what's the fun in that? |
|
| |
NB that using pigeons to guide missiles
project...pigeons are pretty expendable, one them
pecking away at a screen in a small plastic rocket
could bring down a drone. |
|
| |
Yes, we know, it's the baby brother of Iron Dome; they're much more up to speed, but it has serious limitations, and the countermeasures are laughably simple to implement. |
|
| |
.... in which case I still suggest the 40mm Bofors exploding round solution.... (see link) |
|

//May we point out that you voted for this ?// The only place where I ever vote for anything is here. I prefer shopping to voting. When you go shopping you get what you want. When you vote, you end up getting what everyone else wants, and I never want what everyone else wants, so why would I ever vote? |
|
| |
// you end up getting what everyone else wants // |
|
| |
Due to the perversity of representative democracy, an obsolete and deeply flawed system, you actually end up getting what nobody wants. It's invariably an unsatisfactory fudge that pleases no-one, not even the majority. |
|
| |
fully baked goods are available at the discount kiosk in the
lobby, please close the door behind you as you leave. |
|
| |
//you actually end up getting what nobody
wants// - maybe - I think in an ideal democracy
you end up getting the thing which doesn’t
completely disgust the largest proportion of the
electorate. If Socrates were here today I’m sure
that’s what he’d say. |
|
| |
He'd probably say a lot of other things first, like "Where am I ?". "Who are all you people ?", and "What, the Greek government STILL have a budget deficit ? HOW much ?" |
|
| |
Ah yes ... that goes along with physics teaching, with such helpful assumptions as "neglecting air resistance", "with a coefficient of restitution of exactly 1", and "where gravitational acceleration is 10 m/s^2 irrespective of depth or altitude". |
|
| |
Also, why is this idea confined to the provision of
on-call falconers just for airports? Where we really
need
on-call falconers is to attack and destroy the
umbrellas of people who walk down busy shopping
streets with these ghastly things open and
blinding/gouging every person passing by. |
|
| |
We suggest you purchase a pack of cigartettes, a Zippo lighter, and two squeezy cans of Zippo lighter fluid. |
|
| |
Umbrellas, even when damp, are delightfully flammable - if you apply a splash of volatile accelerant and then an ignition source. Once the canopy has burnt away, the umbrella is of no further use and will probably be discarded. |
|
| |
If you are challenged, the cigarettes are a decoy. Explain that you are a smoker, you use a Zippo lighter, and you have just purchased a fresh can of fuel. When you get home, refill the can you carry from the other one, so that it always seems full and "new", thus deflecting suspicion. |
|
| |
The latest theory is that it was a cluster of pigeons
who have learned how to fly in tight formation,
thereby resembling a drone shape. Not to be
outdone, a jumbo jet profiled murmuration is
being worked on by a nearby flock of starlings. |
|
| |
// The smallest AAA round that can mount a prox fuse is a
75mm. // |
|
| |
But you don't need one if you get the range from radar and
use programmable airburst rounds [link] (which are actually
pretty common now according to my few seconds of looking-
up). |
|
| |
It's a possibility, although scattering metallic FOD all over an airfield is less than popular. |
|
| |
Variants using an etched copper wire inside a thin-walled projectile, similar to a frag grenade, have been investigated, but no conclusions yet. Although they can knock down a drone, they can't be used anywhere near an aircraft, and current doctrine means that if a drone is spotted all aircraft in the vicinity shut down their main engines immediately and wait for a tow back to the stand. |
|
| |
There's a school of thought that points out that having always-live semi-autonomous radar-directed autocannon installations sprinkled around a civilian airport might be only slightly less dangerous than any putative drone incursion ... |
