1st off, let's wish 3rd Warrant Officer Jeffrey Heng, a member of our heroic Commandos, a speedy recovery & thank him for his efforts. He is our citizen & fellow Human. We Singaporeans leave no one behind, a bond we all made with our sacred National Pledge we swore daily since 6 yrs old.
Free fall parachuting-jumping out of a moving plane at 10,000ft is not an easy task, needs much training as well as many other factors for success including even capricious Nature environment. As he was the last jumper, the aerial vessel, after dropping off 9 other jumpers, would had moved several if not hundreds of ft away from the target drop zone due to wind & pressure from Nature, rather erratic lately with thunderstorms, sunny weather, haze & heat rising from the surface, thus the last parachutist would have to speed up, manoeuvre his flight to the drop zone quickly or else he would miss the drop zone.
Such incidents are common in real life missions. No matter how much is planned & calculated, no mortal can predict minutely how Nature will act in peacetime, & worse in wars as the unfathomable fuzzy logic of Human reactions would be another inclusive factor, thus the silent un-trackable free fall method is a dangerous operation which only the best of courageous men would undertake when nations go into conflict, on missions to save lives & loved ones, that no drone can undertake due to the nature of necessary hands-on operations in later stages of missions that no robot can perform.
That this capability is displayed on NDP is not meant to show off for fun, but to assure our citizens & those from foreign nations that think Spore is just a mere prawn, that we Spore have such abilities, with not just 9 men whom safely landed on the target drop zone, but even another whom will try hard despite any difficulties, to make it to the drop zone & complete their mission of the day. Extrapolate it to the hundred thousands of men whom served NS regularly, we may be shrimps, but fully trained & mentally armored, so think again that we are presumed easily swallowed shrimps.
