Knowledgeable Flight Radar 24 people. What's at Gatwick?

[megletthesecond]

I'm sure they're not flying squares but I can't figure out what they are. Works-number something or other .

There's an issue with a drone apparently. All flights have been delayed or rerouted.

Are they not some type of ground vehicles, i.e. the buses taking passengers to planes or for shunting luggage about?

Oh god. I've just realised that I've answered a question that you didn't even ask!

Twitter says two drones in the airspace

Drones

French maybe they're something to do with it.
converse I wondered ground vehicle too but I don't recall seeing them anywhere else.

Yes, ground vehicles. ATC have to know where they are so they don't plonk an A380 on top of them (and so they can cross the runway)

They are elsewhere, they just aren't visible to FR24

One of them is called "Follow Me"

Yes, they’re ground vehicles. Other airports don’t seem to have them on radar. No idea why!

Also showing at BHX.

Ones the 'Leader'.

I bet the staff constantly curse those who named the ground. Although I guess you could have some fun too
