This is a big question. Not sure if I can answer that one and it goes on and on

[slinky]

Do we have to have the same question every time a thread gets a new volume??

"Things you always wanted to know the answer to"

It would seem so

[Tyre Tread]

Why is it likely that this thread will die now its lost its natural flow?

2 part question first part I suspect has been asked before.
Is there a minimum speed needed to keep a plane in the air? I geuess it will vary by aircraft so lets say a Britten-Norman Islander.
2ns part, why do some police use these instead of choppers? If a planes minimum speed is higher than the car its chasing will it not just have to keep circling in order to not blast past it

Yes

and

Cheaper

To add to that, planes are also a hell of a lot more fuel efficient that choppers. Quite often however they will have a plane on standby to take over from the chopper if it gets to bingo fuel.

On roadworks (M62) you have the little amber lights on top of the cones. Every now and again there are purple (maybe UV?) ones... is this just the cones indicating if they're toppers or something less gay?

and how do they flash in order like runway lights without losing synchronisation, unless they are all wired together...

I should have just told you to google it.

Could a cyclist set a red light camera off?

IIRC it's a simple wireless transmitter and receiver, the old ones used to have a light sensor but they only worked in the dark, the wireless means that different patterns can be set.

A useless bit of trivia to that is, i once speed matched a set of those lights and found that the flashing light travelled at 127mph

Surely that would depend on how far apart the cones were.

[Aizle]

Well if he was driving at 127mph and the light was travelling with him, it would appear the light was doing 127mph.

ETA - Now I'm properly awake I see your point. I wonder if they can tell how far apart they are and flash at "127mph" ish.

Just read on google that apparently it's just a IR sensor and sender either side of the lamp.. Front picks up the signal from the rear of the one in front of it, flashes and sends a signal out of the back to the one behind it..

Is there an underwater speed record?
