Combining these two with the experimental approximate scaling law, we get:

Z = 12.73 m * (V / 1 m3)^ (1/3)

=>

V = 1 m * (Z / 12.73 m)^3 ~ 0.5 m3 ~ 1.95 kg fuel ~ 2 kg

The math seems to add about up. With 110 kg, the plume due to the initial fireball would have been about four times larger in height.

We will never know until the investigation is done, my friend. I'm just glad that Romain "The Phoenix" Grojean is safe.

The announcers claimed that the fuel collector only retains 2 liters, which is substantially less than 3 gallons. Were they incorrect? I know nothing of this collector.
