Was flying the " take off quick mission " in nttr. I had landed back at Ellis opened the canopy and taxied back to take off again. I tried to make sure the lock was engaged. I could not confirm the movement to the locked position. Anyway, once I took off the canopy popped off. A second later it reappeared, once I hit 250kts it disappeared again and again once i got under 250 knots it reappeared.
