I was on the terace of our house with my dad and mom talking. then my dad suddenly told me to look in the sky fast and i was reluctant thinking he was pointing me to a plane. still i looked and saw an object with a shape in between "v" and "u" sailing accross the clouds at incredible speed. dad suggested that it could be a missile but we both dismissed the idea as it was not that fast and there was no emmion or trail behind. it was too big (football ground size) to be any commercial aeroplane. based on the shape it could not be classified to any known flying objects. then suddenly as we looked it gained more speed, in few seconds took a 'u' to the south and gained altitude as it disappeared. i could not go down and get my camcoder as all this happend in less than 30 seconds. i do not believe in ufo or such hoax but this was beyond our comprehension. also my explanation of his experience of the sighting is same as mine. i asked him to explain exately as he saw and it was same as mine. i did it so see if it was my imagination. i also never intented to report it to anyone but after searching the internet found that some others also had sighted cheveron shaped craft. so i thougt it might be of some relevance to report it. i still do not think that it is any alien but i think one of the nations might be testing advanced aircraft with the size of a football ground.
