Aircraft

I looked back and to my left out a rearward window to see the T6 coming down on top of us.

We were over the runway at about 15 feet AGL when the engine went quiet. The right wing dropped and we lost all lift without hearing the stall horn.

Upon takeoff roll, noticed airspeed indicator not showing airspeed.

My student said they were close enough to see the people in the other cockpit.

I didn’t want to be “the guy who screwed up the OSH departure and snarled traffic for everyone.”

I did not spot the aircraft until it was roughly 100 feet away, at which point I took evasive action and dove my aircraft.

All of a sudden I caught a glimpse of the Skyhawk banking away from me. I never saw him until he was off my left wing at the same altitude.

When I got home that night, I looked up what a “low approach” meant and I was shocked, scared, and embarrassed.

A few minutes later we hit severe wake turbulence, causing the airplane to violently roll to the left while losing altitude. I reacted quickly and kept the airplane level and under control.
