...from my brother, a pilot for FedEx:
$this->bbcode_second_pass_quote('', 'I') had my longest flight of my career this week.. Memphis to Narita
(Tokyo), Japan.

Here are some numbers:

Show time for the trip: 1:57 am CDT

Time from push back to setting the parking brake at destination: 13:33

Weight of the jet at takeoff: 585,000 lbs.

Number of pounds of fuel at start: 256,000

Number of pounds at engine shutdown: 34,000

Fuel used (gallons): 33,134

Pounds of freight moved: 80,000

Number of First Officers: 3

Number of breaks: 2 three hour breaks for 2 pilots at a time.

Number of hours sleep I got during my breaks: 4 total.

Feet above the ground when the approach lights came into sight: 300.

Number of hours layover at Narita: 30

Number of hours I slept during that layover: 16
(and I never left the hotel.)


And that's just one flight. Wow.

Think I should telll him about PO?

He has also told me that FedEx owns at least one refinery.

In terms of efficiency picture the thousands of large aircraft each burning 30,000 plus gallons of kerosene based jet fuel flying between continents every day, seven days a week. They all have to make round trips of double that to get back to their home airfield. They are fast, but heavier than air craft are very fuel intensive.

The Hindenberg had a 19,500 gallon capacity of kerosene and was able to easily fly from Germany to Argentina. Granted the trip took a lot longer, but so what? The whole idea of just in time shipping will be impractical with high fuel costs, the whole system thrives on economies of scale coupled with cheap fuel.

I often think.....What is Boeing thinking?

There whole business model must be based upon denial.

Without doing the maths fully- the Hindenberg comparison is an obvious flop- 80,000 pounds cargo???

Probably the most efficient potential schedulable intercontinental travel in theory would be the WIG effect craft. Lighter than air vehicles are only efficient when moving with the wind near windspeed. Too much surface area and resistance.

No aircraft is a good cargo option really, first place goes to water shipping, second place to rail on land. The smaller the mehod of moving cargo the less conomy of scale and aircraft just can't compete on an energy efficiency basis with ships and trains. You can say the same thing about passengers but humans are often willing to waste energ to save time. If I go on vacation I want to spend as much time as possible at my destination and as little as possible traveling too and fro.

WIG craft give you higher speed than ship or rail without a huge loss in efficiency gaining and then losing altitude, probably not a bad compromise for medium distance passenger movement.

Totally agree. A point Orlov emphasizes besides the massive fuel-mass-miles savings of maritime freight- is the relative lack of infrastructure maintenance required, Rail track maintenence for carrying capacity must be vastly more efficient than road infrastructure also. WIG effect craft and gyro copters could replace a lot of emergency service vehicles in a post road infrastructure collapse (something I see as inevitable under eventual energy constraints- even the most efficient vehicles on wheels require very expensive roads infrastructure in $ and energy terms.
