Human Factors
On date I was conducting training in an R22 Helicopter departing out of ZZZ at XA:45 local time to ZZZ1. Winds were predominantly out of the west at around 10 kts and we joined left closed traffic for RWY 26 at ZZZ1. There was high training volume and I estimate 7 aircraft were on the ground waiting to depart or actively in the Right Closed Traffic for RWY XX plus our Helicopter. At around XB:10 local time a Jet taxied to the active with no Radio (or no radio communication was made) as we were on a left downwind for [Runway] XX. Local pilots made calls on the radio so all would be aware of his departure and be vigilant/use caution. The jet took off without incident and departed to the North. As pilots worked together to sequence traffic we made our base and final leg before again departing XX to rejoin left closed traffic. At approximately XB:15 local time on the upwind of XX roughly 300ft AGL without warning the jet made a low pass on runway XY at very high speed. I would estimate the pilot was 300ft off our starboard side and about 100ft below our current altitude. I was able to track his flight after the incident to find his Ground Speed was in excess of 330mph. The Jet than proceeded back out to the North again and ended up circling to land on RWY XY this time to a full stop. (The following is my personal opinion) I believe this pilot does not have any remorse for his action. He has an attitude that the FAA can't/won't get him in trouble for this reckless behavior. He wasn't breaking any REG by operating without a radio in an ECHO airspace but his speed certainly was in violation of FAR 91.117(a) and given the high training volume being conducted on this day the pilot showed a clear disregard for other pilots or even his/her own safety.
Helicopter pilot reported an NMAC in the traffic pattern when a jet trainer made an unannounced high-speed low pass over the runway next to the helicopter.
