Israeli F-16 pilot's greatest threat not Iranian air defenses, but cancer

The Israeli Air Force has grounded its entire fleet of 62 Lockheed Martin F-16I Sufas after it discovered formaldehyde in the cockpit. Known to cause cancer at certain concentrations, it is unclear as to how the formaldehyde, a by-product of jet exhaust, is entering the cockpit. Lockheed Martin officials are working closely with the IAF and have a suspicion that the chemical may be entering the cockpit through the air conditioning system. The IAF did not ground its fleet of F-16C/Ds and this problem has not been reported by any other operator of the aircraft. It does,however, have many IAF pilots concerned and rightly so.
