On the morning of 18/10/2021 my daughter my dog and my self were in a local forest livingston state forest we walked down the side of ahill we have walked 30 times before . The track we walk down is not actually a path just a general path we veer through the trees .we walked down on this morning about 80m and stoped had a drink through the stick around for about 10 minutes and decide to head back , we were about 10 metres away from the spot where we were just sitting when all of a sudden from behind my daughter my dog and i were forced down in a hunched position the trees moved outward in a parting motion. Leaves were moved outward like aleaf blower were moving them . But there was no wind ,it was not heard at all till it was about twn metres bihind us, when we heard it it was a real loud humming sound with a electric zapping like a tesla coil. The sound was like a huge amount of rushing air but without the wind . It flew above us about 15 foot it went about! 40 metres in front of us and veared slightly to the right and was that quick going up it could not posably be a drone of any type .the thing that i witnessed was realy small about 4 foot triangular shaped with realy dark grey colour ,it looked like a mini version of a stealth bomber. It was like it swooped us and once it was gone my dog ran off , we were both shakin standing there it felt like when you get up real quick you get a head spin my daughter asked me what it was and i cannot tell her .my daughter is 11 and im 43 years of age.
