@vgr The other pro-airplane take is simply that HSR requires consensus-layer changes to L1 whereas airplanes are mostly L2 with relatively lighter L1 work required (pushing to change FAA and a few other regs), and doing things at L2 is 10x easier.

@vgr 另一个亲飞机的做法是，HSR 需要对 L1 进行共识层更改，而飞机大多是 L2，需要相对较轻的 L1 工作（推动更改 FAA 和其他一些规则），并且在 L2 上做事要容易 10 倍.
