Dashcam video speed information
Following the discussion of the debris speed, but without looking to check the numbers from earlier posts this is what I reckon.
The aircraft's visible diving down the bank to the right before the debris arrives, and seems to be moving quickly enough to cover its length in a couple of seconds, which would be about 20-25 m/s, about 40-50 knots. It definitely doesn't look like 100 knots. It seems to be driving not flying.
The wheel bounces off the bottom of the light gantry, crossing four lanes of the road in what looks like a bit more than two seconds - that's only about 10 m/s, so the wheel I reckon is moving slower than the aircraft was when it was released.
To correct both of these numbers, there's the factor of almost 45 degrees that the runway is angled with the road, so both should be higher by about 1.4.
I'd guess about 35 +- 15 knots for the wheel, and 60 +- 20 knots for the aircraft.
