privacy data omitted Arrived at the Morrisville-Stowe State airport (kmvl) at approximately 1000 hours on 09/03/2020 in a 1950 Cessna 170A N170JS.
The accident flight was preceded by a series of normal takeoffs and landings (touch and goes) on the grass runway adjacent to runway 01/19. The final take-off was to the north. The accident site was between runway 10/19 and the parallel grass runway approximately at the midpoint of runway 01/19.

privacy data omitted Statement:
?Last Thursday, I flew to Morrisville airport to help provide demonstration to a friend who had started taking lessons in the 170 with a tailwheel certified instructor. He was having difficulties with take offs and landings and I thought by seeing repetitions of the ?vision? It might be helpful for his next lesson. Winds were light out of the north. I utilized the grass landing area for several take-offs, all without incident. During this particular take off (a short field procedure with two notches of flaps, brakes, aft yoke and full power), after releasing the brakes, the airplane veered toward the ditch in between the grass and the asphalt. I attempted to steer away from the ditch with rudder, but was unable and with the ditch looming ahead and with what I thought was sufficient airspeed I rotated and then stalled to the left.?
N170JS came to rest facing an easterly direction on the west edge of runway 01/19. A significant amount of fuel was leaking from the left tank and from the underside of the engine. Both occupants were initially unresponsive and injured.
The main gear was crushed backwards and the forward section of the fuselage belly dented in. There was rotational damage to the propeller and damage to the engine cowl and compartment. The left wingtip was crumpled up and the root was torn and crumpled. The right wing tip was crumpled down. The aft fuselage area and empennage appeared undamaged.
