The Russian pilot of the MiG-21 that crashed on the 15th was reportedly seen "drinking heavily" the night before the crash, but the army spokesman said that there was no credible information of that charge. International navigation regulations prohibit pilots from operating an aircraft (or performing other safety sensitive functions) within eight hours of consuming alcohol, or if they have an alcohol concentration of 0.04 or higher. Witnesses also reported that the pilot was engaged in aerobics over water, contrary to normal practice. - Adam Geibel
