I've been curious to see the size difference between the F-22 (Starscream's alt-mode) and the SR71 (Jetfire's alt-mode), so I decided to make a comparison photo of my own. The SR71 is significantly bigger than the F-22, though that's not surprising. I've actually seen an SR71 up close in person, and, it may have just been me, but it doesn't actually seem all that big when you see it in person. Though that might have been the difference in angle when you're looking at it from the side than when you look at it from the top. Should be interesting to see how big Jetfire is in bot-mode. Especially compared to Optimus Prime.
