Bright Red UFO over North London with incredible manoeuvering capabilities.Bright red light, came towards us at high rate of speed (faster than anything conventional I have seen), moving at low altitude (approx. 200-300 feet up), with no engine sound, or trails. Without any sign of slowing down, it came to an immediate stop. Hovered for a about 5 seconds, before shooting off at instantaneous massive speed in a 90 degree angle to its previous flight path, all the time with its red light pointing toward us (it didn't bank or rotate, the front of the craft was facing us at all times).. It repeated the same manoeuvres as before (each time flying off at 90 degree flight paths to its prior flight path) two more times, doing same as before.. instant acceleration, then instant stop, before finally shooting instantly off at incredible speed and out of sight. Its movements were perfect, no banking or turning, constant altitude, extreme acceleration and stopping capabilities. All in all this was quite a close encounter as it was at all times within! the immediate location of where we are, almost as if it was showing off for us.((NUFORC Note: We spoke via telephone with the witness, and he sounded to us to be quite serious-minded. We suspect that he is a highly reliable, and capable, witness. PD))
