The water reflections shown in your examples are not very realistic at all and are probably created in at least two different reflection layers, one for the distortion and another for the more in focus reflection and then they are blended using layer masks.
I understand what the original artist was shooting for, but the distortion he/she is trying to simulate is associated more with heavier ripples in the water. Rippled water causes what's called diffuse reflection. In essence, think of it as each ripple is an individual mirror and each ripple reflects the entirety of the subject. This is what causes the elongated reflections you would see in images photographed at a greater distance.
Here notice how the moon is reflected in it's entirety in each ripple:

Rippled water causes the elongated reflection.

This one gives an example of both, rippled water closer in and calm water further out.

Here's another example of calm water:

In your example, the subject (plane) was photographed fairly close in and in calm still water. The reflection would be very crisp. Even if the water were slightly rippled, you would not have the exaggerated elongated distortion you see in your plane examples.
The closer you are to your subject and in calm water, your just not going to have that exaggerated elongated reflection.
