Unless you are on the center-line of the approach, you rarely get to see the aircraft directly head on. If there is a crosswind from your direction, though, you can get the planes pointing straight at you for a while. Sadly, this usually is while they are further out on the approach. If you are closer to the runway then you can get a shot that is more interesting because there is some ground to provide context to the angle of the plane. With a strong enough crosswind, you can get a head on shot until close to touchdown.
There is a location that I shot at once that is no longer available. It provided a good opportunity to get shots on a strong crosswind day. A Cathay Pacific 777-300ER demonstrates what I mean. A long airliner like a 777 emphasizes the effect even better when it swings around just before touchdown. The photos don’t demonstrate that as well as a video would but it did look cool. It wasn’t the only one either!
