In terms of specs, the fighter jet that is used is an F-35B, which is a Lightning II variant that makes use of thrust vectoring for incredibly short take offs and vertical landings.

Estimates of around 2.5 seconds to 100kmh have been made as McLaren hasn't released full performance times just yet. It can hit 300km/h in 12 seconds before topping out at 403km/h, though, making it the fastest McLaren yet.
But what happens when all this on-road performance is put up against an airborne speedster? You'll have to watch the video to find out.
