Optimizing taxiing procedure in departure and arrivial in Mission 05?

[Polonsky]

When departing from the hanger I head straight and turn right for RWY05, and I have to maintain a relatively quick taxiing speed to avoid the humvee that initially stopping in front of the wingman bumping into my back engines as it will chase me on the same route with at a certain speed. That's how I failed the mission in the first attempt. Any way to improve this?

After landing, I was prompt to taxi to slot 19 (or 18, I forgot), I end up in the place like this

It's a dead end labeled 19 on the AIRPORT DIAGRAM and I received no further prompt that I've received the destination.
