Answer to:
At what speed are fighter pilots ejected during an emergency? The Martin Baker Type 10A Ejector Seat used in all Tornado aircraft accelerates from 0-100mph in 0.4 seconds. In reaction to the response 'but at what speed are pilots ejected?', I say that the aircraft can be travelling at any speed within its capability, and the pilot is at this speed when he is ejected, although a pilot hates to lose his aircraft, so will spend as long as...

Answer to:
What is the world speed record for a helicopter? A chopper was converted from Westland's own Lynx AH.1 demonstrator to the only Lynx 800 in an attempt to break the helicopter world speed record. Carrying the registration G-LYNX, it broke the record on 11th August 1986 with a final speed of 249.09 mph (kmh). The Westland Lynx in question was specially modified to achieve the 400.55kmh speed, including special rotor blades (British...

Answer to:
Some people insist that American cars are mechanically inferior to Japanese cars. Others have told me that this used to be the case, but is no longer so. Who's right? European engines, for example, generally are more fuel efficient, and achieve higher power outputs from the same displacement. This is partly to do with US cars running at lower compression ratios, although fuel ratings may also cause some differences. A higher amount of 'highway' driving rather than in city traffic, couple with lower compression ratios also means that they last...

Answer to:
What's the difference between American baseball and British cricket? Kind of an opposite answer to the question, but anyway! The distance between the two creases in cricket (i.e. bowler's release point to [generally] the batsmen's start point) is the same as the distance between the pitcher and the hitter (22 yards), which is also the distance between the bases.

Answer to:
What are the slope skill ratings, and what do they mean? The European system rates the easiest slopes as green, moderate as blue, difficult as red and very difficult as black. There is no diamond system in Europe, although there are 'ski trails' in some countries, which are not pisted, but are monitored by the mountain patrols. The difference is that in the USA, you can safely ski almost everywhere with the ski area boundary, whereas in...

Answer to:
Why do Americans call soccer (a sport played with foot) "soccer" while calling football (a sport played with the hands) "football"? 'Soccer' can not have been used before 'football', as otherwise the Football As'soc'iation would not have been named so. I will concur, though, that 'soccer' was used in Britain before the US. Maybe I wasn't eloquent: the word 'association' was certainly not named after the sport, but before the sport, from French meaning congregate or...

Answer to:
In rally, what is a "herringbone"? In navigational rallies, the team has to work their route at the start of each stage. A herringbone is one example of the logic clue provided, representing turnings from start to finish of the section, drawn with the route in a straight line (the 'spine'), with the turnings not taken as smaller 'bones' coming off on either side. A more complex version is a circular...

Answer to:
What are common snowboarding injuries, and how can I avoid them? When learning, common injuries are a bruised bum and sprained (or broken) wrists. These occur when falling heelwise (or backwards) and toewise (forwards) respectively. I would recommend wrist protectors, which are steel shafts embedded into a glove of some sort, preferably on the inside and outside of the wrist. These are also used in roller blading. There are some hilarious pieces of...

Answer to:
How many en passant movements are allowed in a chess game? The en passent (in passing) move can only be used straight after a pawn has moved two spaces on its initial move, so each pawn can only make the move once (it has to be ready and in the correct position, which it loses after it has made the move). I suppose there is a theoretical maximum number of times it could take place in one game (for all pawns), but while this might be a nice,...

Answer to:
Are there any good etiquette guides for children who are between the ages of 3-5? Yes - their parents. If you take a question like this seriously, more fool you. How many three to five year olds could read a 'good etiquette' guide, and understand what it meant. Their parents whould be teaching them at that age, and the parents should not need a book to read on what good etiquette is for children of three to five years old. Just getting them not to bite or kick...

Answer to:
When you leave the table during a meal, should you place your napkin on the table or on your seat? You should leave your serviette on your chair, out of view of the other diners. Interesting that all comments here say that this is 'just wrong', when my answer agrees with Hp-frreeze's answer, and that has an A+ rating. Think about it.
