Hawks and Mirkos bare minimum Travel speed.
So Mirko and Jeanist are stated to be faster than this airlift type jet jeanist was in. The question is how much faster and what would that equate to. I will be calculating this now.
Jeanist states wanting to be there in 5 minutes and the driver states he can't do that it's not like they're Mirko or Hawks. This means Hawks or Mirko can travel that distance faster. Finding out how much faster and how fast the plane is too.
So it's stated Machia will reach near the zone in 10 minutes after we see jeanist and the plane. We get this graph type shot showing the 10 minutes mark and then how far away it is from the remains where shiggy is fighting everyone which is marked up there. I'll use the distance between Machia and the 10 minute mark then the distance between the mark and the fight position to find the time between that. Then after Machia arrives it takes 13 minutes and 45 seconds for jeanist to show.
Time it took the plane to get there
825+600+245=1670s
I've looked at many sources, asked others. This plane shown doesn't exactly reference any specific plane irl but it does slightly of some. It also clearly has the same features and purpose and some real life Aircrafts just appearing more futuristic. It's clearly an airlifter.
So going of some similarities I'll use a Boeing C-17. Tho this one is likely faster given it's more futuristic design and mha military grade tech being far above ours.
Plane speed: Mach 0.875
Timeframe for Mirko and Hawks: 300s
Timeframe for plane: 1670s
Speed difference: 1670÷300=5.57
Hawks and Mirko bare minimum travel speed: 5.57×0.875=Mach4.87 which is in the Supersonic+ ranges of speed.
Thats nice just boardering the Hypersonic speed. Tho obviously this is huge low ball and they scale to feats waaaay above this it's nice to just get a bare minimum especially for travel speed. This is hella consistent for Hawks and Mirko too who are 2 of the fastest characters in the verse so I don't see how anyone can or would deny this.
Tho I will note that Hawks is a significant gap above Mirko in speed so that I don't give people the idea they're equal. For example Hawks is equal to hood the strongest and fastest high end in speed. Meanwhile the high ends Mirko fought were already faster then her after a few minutes of waking up when they should need like 10 hours to fully wake up.
