Orange pulsing fireball

Orange pulsing fire ball witnessed by two people hovering and moving slowly right 50 feet, upwards 20 feet down 20 feet, for 15 mins, at this point another object appeared at high speed from the right and stopped next to the first object, following for about 5 mins and then disappeared leaving the first object still in view for further 2-3 mins before also disappearing   I have a pair of 50x80 binoculars, the object was in line and in view with a pylon this making the movements visible clearly,  I tried to take footage on my mobile phone however you can make out the pulsing but no definate shape . . shame . .
