Sure, but ... thats not a spec. Specs have clear goals and limited scope. "All flights from all airports forever" is impossible to program, full stop.

The right way to write code like that is to start simple and small - we're going to service airports X, Y and Z. Those airports handle Q planes per day. The software will be used by (this user group) and have (some set of responsibilities). The software engineers will work with the teams on the ground during and after deployment to make sure the software is fit for purpose. Someone will sign off on using it and trusting its decisions. And lets also do a risk assessment where we lay out all the ways defects in the software could cost money and lives, so we can figure out how risk averse we need to be.

Give me scope like that, and sure - I'll put a team together to write that code. It'll be expensive, but not impossible. And once its working well, I'd happily roll it out to more airports in a controlled and predictable manner.
