Didnt see the other jet photos but these two are faked.
I put both of these through a photo shop analysis.
1st problem is that the jets in each photo are of a differant resolution then the background, that becomes readily apparant at about a 400% blowup. 2nd as I pointed out is that the background does not show through the canopy on either jet, it shows blue sky instead. You could say that it a result of reflected light but that is not the case as the pilots yellow helmet can be seen.
3rd, there is the problem of the disappearing sailboat mast, not only have the mast been erased in the process but it created a sharp 'exhaust' line without the typical wave effect of heat exhaust. The whole area has the tell tell characteristics of the blur tool in photoshop.
Another problem is the shockwave effect on the water. Close inspection shows that it is almost beneath the planes tail section, I'm sure our pilot friends out there will tell you that that wave pattern is not going to follow in lock step with the aircraft.
And, moving right along, there is the vapor trail under the fusalage that has far too sharp an edge on it for a vapor trail.
And to really put it to rest I shot an e-mail off to the Blue Angels via their web site. Will let you know in a few days.
