That's pretty cartoonish - here is the accident investigation report:

The bottom line is that all those involved had exactly zero training in how to do metric fuel load calculations.

If anyone wants to read the book about this (Freefall by William and Marilyn Hoffer) just pay for shipping (~$8) I'll send you mine.

Colour me mystified: what of earth has the Hudson to do with the Gimli
Glider?

The Hudson was Sullenberger's show. BTW, I seem to remember that at the
time he was said to have no glider experience, but that's wrong:
apparently he did have a glider rating at the time and (later?) became a
CFIG, so about the only connection is that the P1 for both the Gimli and
Hudson incidents were glider pilots.

Pardon me playing Captain Obvious, but the both involve landing
airliners with no power and no loss of life. But none of this is
exactly breaking news.

One thing that was interesting from the Gimli incident that wasn't
covered in that clip, the 767 had in-op fuel gauges and was allowed to
make the flight. Not the primary cause of the accident, but would have
provided much earlier notification of a problem than having an engine
flame out.

The last Boeing I flew was the 727 and it had fuel gauges behind a panel
on the under side of the right wing.Â* There was also a calibrated drip
stick.Â* I imagine the 767 has similar provisions and I also imagine that
the aircraft's MEL does not include the fuel gauges in the cockpit.Â* But
then I'm just imagining things...Â* In the first article I read about
this incident, a long time ago, they mentioned the inoperative cockpit
gauges and I think it mentioned that the flight was legal with no
in-cockpit gauges.

That is covered extensively in the accident report. The pilots violated the Minimum Equipment List, making it an illegal flight. The incident would never have occurred if their fuel computer was working, or if they used the correct specific gravity for fuel (they used the value for lb/l instead of kg/l, resulting in the loading of less than half the fuel required).

Tom

Yes, now I recall having read that.

Here's the Cliff Notes version of the report:

They could have had a working fuel gauge if a technician hadn't restored
a circuit breaker as part of a trouble-shooting exercise.

So yes it was not airworthy, but it wasn't as simple as the captain
saying "Screw the MEL, we're going anyway".

Dan,

That was just it. The dripsticks do read in Pounds, and the crew
thought that because they were in Canada, the sticks would be
reading in Kilos. The crew assumed wrong by a factor of 2.2,
so they had less than half the fuel than they thought when they
had finished fueling. Lots of errors... Obviously no before fueling
dripstick readings, or paper calculations after getting the fuel offload
receipt from the fuel truck, etc....
