Narrative:

I obtained ATIS while under VFR flight following. After being released by center, I called lacrosse tower 12 mi out and was told to 'report 2 mi west, runway 22.' after continuing inbound, we (my private pilot rated spouse) heard flight of 2 edges (approximately 8 mi) report 'request straight-in, runway 3 with a low overhead.' to which the tower responded 'approved, left turn for re-entry.' my spouse said 'he just turned them into us. Call the tower, we are 2.5 mi out, where are the edges?' 'there they are' (edges were approximately 100 ft above and 200 ft to our left, passing directly over us). No evasive action was taken by any aircraft. The edges were on a left downwind for runway 3. I called the tower to tell him 'the edges just passed over the top of us, what do you want us to do now?' the tower responded 'oh, well let's see -- just follow them.'

Original NASA ASRS Text

Title: AN EXPERIMENTAL RV6 PLT AND PAX ARE SUBJECTED TO AN NMAC BY A FLT OF 2 ZIVCO 'EDGES' ACROBATIC ACFT THAT WERE PERMITTED TO PERFORM A LOW OVERHEAD, STRAIGHT-IN RUN TO RWY 3 BY LCL CTLR AT LSE, WI.

Narrative: I OBTAINED ATIS WHILE UNDER VFR FLT FOLLOWING. AFTER BEING RELEASED BY CTR, I CALLED LACROSSE TWR 12 MI OUT AND WAS TOLD TO 'RPT 2 MI W, RWY 22.' AFTER CONTINUING INBOUND, WE (MY PVT PLT RATED SPOUSE) HEARD FLT OF 2 EDGES (APPROX 8 MI) RPT 'REQUEST STRAIGHT-IN, RWY 3 WITH A LOW OVERHEAD.' TO WHICH THE TWR RESPONDED 'APPROVED, L TURN FOR RE-ENTRY.' MY SPOUSE SAID 'HE JUST TURNED THEM INTO US. CALL THE TWR, WE ARE 2.5 MI OUT, WHERE ARE THE EDGES?' 'THERE THEY ARE' (EDGES WERE APPROX 100 FT ABOVE AND 200 FT TO OUR L, PASSING DIRECTLY OVER US). NO EVASIVE ACTION WAS TAKEN BY ANY ACFT. THE EDGES WERE ON A L DOWNWIND FOR RWY 3. I CALLED THE TWR TO TELL HIM 'THE EDGES JUST PASSED OVER THE TOP OF US, WHAT DO YOU WANT US TO DO NOW?' THE TWR RESPONDED 'OH, WELL LET'S SEE -- JUST FOLLOW THEM.'
