Carcinogenic materials discovered in two more F-16I jets

Carcinogenic materials were discovered in two more F-16I jets, it was reported Monday overnight. Of 10 F-16s tested so far, three have been discovered to contain formaldehyde. Results were still pending for 10 more planes. IAF Commander Maj.-Gen. Elazar Shkedy grounded all F-16I training flights earlier in March after the carcinogenic material was found in the cockpit of one of the aircraft.
