That last one is superb.

I love the Lightning. I used to study the one at Hendon for ages, when I way a kid. Amazing aircraft, I think it was the first (only?) plane that could break the sound barrier from take-off in a vertical climb.

The Lightning possessed a remarkable climb rate, and its time to reach an altitude, or time-to-climb, was exceptional. To achieve this short time-to-climb, Lightnings employed a particular climb profile, which was more shallow in angle compared to that demonstrated at air shows. The Lightning was famous for its ability to rapidly rotate at the end of the runway and climb almost vertically away, but although this near-vertical climb was impressive, it did not yield the best time to altitude, nor was it a demonstration of the ability to sustain a vertical climb. When Lightning pilots performed their trademark tail-stand, they were actually trading airspeed for altitude. The Lightnings would seemingly zoom “out of sight,” accelerating away, when in fact they would slow to near stall before pushing over into level flight. During the optimum time-to-climb profile, the maximum climb angle never exceeded 30 degrees.

The Lightning’s optimum climb profile began with an afterburner takeoff. Immediately after takeoff, the landing gear would be retracted and the nose held down to allow rapid acceleration to 430 KIAS, then a climb initiated and stabilized at 450 KIAS. At this IAS, the climb rate would be constant at approximately 20,000 ft/min.,[5][nb 9] The Lightning would reach Mach 0.87 at 13,000 ft.[nb 10] The pilot would then maintain Mach 0.87 until the tropopause, 36,000 ft. on a standard day. The climb rate would decrease during the constant-Mach portion of the profile.[nb 11] If further climb were required, the Lightning would accelerate to supersonic speed at the tropopause prior to resuming the climb at supersonic speed.[5][7]

A Lightning flying its optimum climb profile would reach 36,000 ft less than 3 minutes after brake release.[5] This was—and is—impressive performance. That the Lightning never reached the climb rates of some of its contemporaries during this profile was not important; that it reached altitude quickly, was.
