The octane rating in jet fuel is pretty high and a lot of additives has been added to give it a high flamepoint. Most fighters actually use the fuel to cool different stuff down so it can get pretty hot. <br /> <br />runhttp://aircraftbargains.com/cs/forums/thread/866.aspxSun, 03 Oct 1999 06:49:00 GMTa23efcf1-9e75-4ff9-be18-cd9cb68b9485:866Anonymous0http://aircraftbargains.com/cs/forums/thread/866.aspxhttp://aircraftbargains.com/cs/forums/commentrss.aspx?SectionID=15&PostID=866*** Posted by Rapier *** <br />Hi Chris, <br /> <br />I'm not sure of the fuel composition but I think it is similar to the fuel used in F1 cars. With regards to the fuel used in the SR-71, it's true that a match will not ignite it if it's dropped on it. The fuel used was called JP-7 which had a high flash point but it was mainly developed to cope with the SR-71's heat problems when flying well above supersonic so the plane would not explode, or something like that. <br /> <br />Regards <br /> <br />Rapier <br />http://aircraftbargains.com/cs/forums/thread/867.aspxSun, 03 Oct 1999 06:49:00 GMTa23efcf1-9e75-4ff9-be18-cd9cb68b9485:867Anonymous0http://aircraftbargains.com/cs/forums/thread/867.aspxhttp://aircraftbargains.com/cs/forums/commentrss.aspx?SectionID=15&PostID=867*** Posted by Rapier *** <br />Hi Chris, <br /> <br />I'm not sure of the fuel composition but I think it is similar to the fuel used in F1 cars.
