On 10/8/2010 I just watched 'short fuse' about the 1993 NY Serial Bomber.  In the last 5 minutes of the program an ATF lab checked the bomb residue and found ethylene glycol dinitrate (ONLY formed when dynamite explodes; dynamite is a HIGH explosive).  I have long suspected that some type of glycol ether must be formed with things explode, such as in war-time, and would be the common denominator for military syndromes of this past century ... & back to 14th century:  responsible for 'flu symptoms' NOT a virus.  http://www.valdezlink.com/re/military/petraeusetal.htm
Lots of people can say things but that doesn't make them so . JP4 and Jp5 were both available during the time period  for use in the aircraft engines  they are as identified below.

JP-5, or JP5 (for "Jet Propellant") is a jet fuel that weighs 6.8 pounds per gallon and has a high flash point (min. 60 °C (140 °F)).[1] It was developed in 1952 for use in aircraft stationed aboard aircraft carriers where the risk from fire is particularly great. JP-5 remains the primary jet fuel for most navies. Its NATO code is F-44. It is also called AVCAT. It is specified by MIL-DTL-5624 U (TURBINE FUEL, AVIATION, GRADES JP-4 AND JP-5), last issued on 2004, and meets the British Specification DEF STAN 91-86 AVCAT/FSII (formerly DERD 2452).
 
The JP-4 and JP-5 fuels, covered by the MIL-DTL-5624 U Specification, are intended for use in aircraft turbine engines. These fuels require military unique additives that are necessary in military weapon systems. This requirement is unique to military aircraft, engine designs, and missions.
 
Additionally, JP-5 is a military unique fuel because it must have a flash point substantially higher than commercial aviation turbine fuels. It is stored in large quantities on aircraft carriers and other vessels. The flash point is for safety in these military unique applications.

Freezing point of JP-5 is −46 °C and the flash point > 60°C. It does not contain antistatic agents. It is a yellow liquid, based on kerosene.
 
Other names for JP-5 are NCI-C54784, Fuel oil no. 5, Residual oil no. 5.
 
JP-5 is a complex mixture of hydrocarbons, containing alkanes, naphthenes, and aromatic hydrocarbons.

 If they had been used the aircraft which were spraying the agent orange would have light up the sky with a fire ball because of their flammability when in close proximity to static electricity which is created by aircraft in flight  that's why they have to use grounding straps to keep from having explosions during refueling and in the case of helicopters bust make a ground via cable to something prior to hoisting or lowering personnel.
