"Usually when something burns, it is subsonic and there is very little pressure effect. With high explosives, the rate of burning is extremely rapid and exceeds the speed of sound. As a result of that there is something called "overpressure" - pressure greater than the surrounding atmospheric pressure. Massive overpressure is not needed to cause damage. An excess of 1% can break windows, and an overpressure of 10% can harm or kill people and cause structural damage to buildings. An overpressure of just 2% could break the windows of the aeroplane, and 10% would wreck the aircraft and possibly kill the people in it before it reached the ground. By the time the damage is caused, the chemistry has finished and physics has taken over."
