Comparing DE shaving to aircraft.

Hi all,



Coming from an engineering background, specifically aerospace I find myself making analogous comparisons / contrasting our wonderful hobby to the modern airliners of today. I know this is a weird thing to compare razors to, but in some respects I think it shows to a certain degree how modern society is adapting to changing economic / practical methods of doing things. Anyway, here goes…



Up until about the mid 90’s there was only a limited number of aircraft available to cross the Atlantic Ocean, i.e. London Heathrow to New York JFK etc., usually due to engine power required. Usually this would be done with the behemoths of the sky – the likes of Boeing 747 or Airbus A340. Both are fabulously engineered wide body, 4-engined jets capable of carrying 200 - 300 passengers reasonably efficiently across a large expanse of land and sea. I compare these to the likes of a Mach 3 or Fusion cartridge razor – something that could similarly be considered a finely engineered piece of equipment which given the right preparation can be quite effective. Despite this, we have observed through this site and others that these razors can be overkill – ingrown hairs, expensive to maintain (read: blade price!), the list goes on. Overkill in terms of aircraft would be to use a 747 / A340 for short haul passenger routes – the amount of fuel required and weight carrying aspects of this make it somewhat impractical (these jets would rarely leave the ground unless they are completely full with passengers). Just as a Mach 3 / Fusion can be great, it can work out somewhat inefficient in buying replacement blades, almost as inefficient as fuelling a ‘jumbo-jet’ for a short haul route – almost not worth an airlines time.



Nowadays, with improvements in aircraft engine performance we can very easily cross the Atlantic using just 2 engines. Enter the likes of a Boeing 777 or Airbus A330. Twin engined, these aircraft can carry almost as many passengers and be able to operate just as efficiently on short haul routes – making them somewhat more desirable to modern airlines. I compare this to our wonderful safety razors, where the mentality (at least to me) is why use 3/4/5 mediocre blades where we could use just one / two very sharp and efficient edges? Same with the aircraft – in a modern business sense I imagine airlines would be thinking along the lines of why should we use 4 ok, but maybe outdated engines when we could use just 2 very efficient ones? The only exception to this is the likes of the Airbus A380 – a 4 engined jet that can be used equally efficiently on long and short haul journeys, plus carry slightly more passengers than a 747.



The above is just a random bunch of thoughts I had, but I suppose this could be related to not just aircraft, but most anything in use today, bikes, cars, you name it. Obviously we are using an old system, but we have repeatedly shown that this is an extremely efficient method of doing a difficult job.



Any thoughts gents?
