A bit of thread drift but my father worked for Saunders Roe at Eastliegh where the prototype Skeeter was made.

As a young lad I used to go with him on saturday mornings to work. On this occasion I was admiring the skeeter prototype when all of a sudden the whole perspex? windscreen shattered. my immediate response was, “I did not touch it!!” Dad said dont worry its been doing that a lot lately!!

All Jet A1 contains a certain amount of static dissipator additive SDA for health and safety reasons. pumped fuel generates static, the SDA keeps up the fuel conductivity which suppreses the ability to generate static charges which would other wise result in quite large sparks everytime you pumped the fuel. Which is the last thing you need when refuelling aircraft. That is why all refuelling is done with the aircraft bonded (earthed). to ensure all the refuelling couplings have equipotential.

Metal de activators can be present and some testing used to be required to ensure JetA1 would not corrode silver. Because many years ago a fuel system component in Caravelle aircraft was silver plated and all JetA1 was tested for silver corrosion resistance to ensure the fuel would not degrade this one solitary component-this testing was done for many years because nobody was quite sure when all the Caravelles round the world were out of service.

Biocide is only added infrequently and FSII if added to Jet fuel creates a different spec of fuel entirely which as already has been pointed out is for military aircraft.

Corrosion inhibitors plus FSII cocktail are also not present in Jet A1 but an entirely different spec of fuel again for the military world.

not sure what any of this is to do with the original topic and apologies for the Thread drift.

There is a wealth of difference between Jet A1 and diesel first of all diesel fuel is meant to ignite when its its compressed as in any car diesel engine it . Jet A1 is easier to ignite than diesel but, its not that easy, it needs an ignition source and to be vaporised , but it does not need to be compressed to ignite it just an ignition source.

in the case of the escape of fuel vapour from the jet wing that would have been easy to ignite should there have been an ignition source in its path.

The hose nozzle on the vehicle refuelling hose is set to shut down at a predetermined internal aircraft tank pressure somehwere between 25 and 50 psi in old money this ensures the refueller does not over pressurise and damage the aircraft tank, but in this case with escaping fuel, the nozzle would not see any increase in pressure due to the escape, and hence would not shut down automatically. so what we are seeing here is a simple case of overfilling the tank!!

Concordia

My mother worked at Cunliffe Owens during WW2 and I also have a picture of concordia with my father and other employees lined up against the fusleage, my poicture shows more of the aircraft than this one.

unfortunately I dont have this picture to hand but next time I am at my store I will try and retrieve it.

check your fuel filters- are they blocked? and all fuel connections for air leaks

self sealing fuel tanks

self sealing fuel tanks are still made by FPT industries, a division of GKN near Portsmouth.
