I think they do, but the two main commands issued by TCAS are CLIMB and DIVE, each plane getting one of those, and at the altitude they were at the dive command would be suicide, so it’s apparently suppressed.

I’ve seen the charts on defined helicopter routes, the charts provided by a professional pilot and that route was being followed. They are supposed to depend on vertical separation and it seems as if the helicopter was higher than required by the route. This may not have been as clear from the typical top-down view of…

This is not the first time for an entire nation to FAFO.

Honestly the best space engineers still work with boobs all day. 

I do not like the trend of lighting that concentrates the apparent light source to a tiny dot. While the amount of photons coming my way may be the same or greater, the smaller size is far more difficult to notice. It may appear to be better for the driver, but for everyone else it’s not.

There are a few avoidance activities. One is to clear tree limbs from near powerlines; this looks like the lines contacted the tree and that started the fire. The second is to ensure the lines are insulated so that contact with trees is no problem; the insulation on all the lines in my neighborhood, 50+ years old, has…

Like this?

Just to add, the speed of sound at -55ºC, a typical temp at altitude, is about 660 mph. At altitude they are going about Mach .85, which is no slouch.

On a 007 car the taillights flip down to expose the Spandau’s.

Just to clarify, do not sneak up and shoot cops. I’m just saying their fevered imagination that anyone is hiding in the trunk for the purpose of shooting them is just a stupid fantasy fear. 

How about a follow-up on wrenchers doing good things? 

A bunch of people on YouTube have similar experiences. They give an example of some bit of work they had done that took hours of research, in depth investigation, validation of references on a topic that their channel is dedicated for and they compare what YouTube does with that vs. when they get frustrated at some…

The problem happens because the snow fell while the pavement was warm, cooling the pavement with freezing water until the pavement was freezing, leaving a layer of ice that plows can’t deal with. While one might say - use salt, and salt is a great answer, unless the plow and salt trucks have chains or studs, they…

Not all the way across the Atlantic. 

An upvote for the 2CV. 

The eagle-eyed among you will note that the speed of sound in air is about 767 mph

Practically, and better than a fingerprint, the touch would leave DNA. However, since cops often wear gloves specifically to avoid leaving either finger prints or DNA when planting false evidence, it is simply an old habit from when they used to use the 5 D-Cell flashlight to shatter the tail lamp lens as probable…

There -should- be. But wouldn’t it be fun to check on buying a used car and see it spent 3 months in a wrecking yard before being bought at auction and sent to Mexico to get a bit of work done? 

Most any vehicle on the street, even without a license plate, can be examined for the VIN.

All motorcycles have friction drive. Try to use one on a surface with no friction.
