The Canon P&S will do you but you have to ask yourself, "How serious am I and how far ahead do I want to look?".
Buying a good P&S only to discover its limitations and subsequently wanting to upgrade to a DSLR is a pointless exercise - you may as well just plump for a DSLR from the outset. On the other hand, spending all that money on a DSLR only to find this hobby isn't for you will make you wish you had bought a P&S in the first place.
If you do decide on a DSLR, here's my advice.....

from what I understand the Canons are much better, especially for aviation.
Firstly, I'm a Canon shooter, and they seem to work best for me. But it's common knowledge that there's virtually nothing in it between the two manufacturers - they both excel in certain fields and both have their pros and cons. What I can say for sure is that the Canons have always had the reputation of handling noise (grain in old 35mm terms) slightly better than the Nikons, and at high ISOs this is noticeable. Having said that, it's generally accepted that Nikons are of a slightly better build quality than the Canons. One thing I particularly like about Canon is the immense choice of lenses available, catering for every taste and budget.
The 450D is without doubt the natural choice when compared to the budget Nikons (i.e. D40, D50 and D60). In fact, it may be worth grabbing a cheap(er) 400D and investing what you save in some decent lenses. I'd personally buy body only, as the 18-55 (for me) lacks range and quality. I use a twin lens combo at the moment - Canon EF28-105 F3.5-4.5 USM II
and EF70-200 F4 L - both unfortunately not cheap lenses, however the skill of the photographer is usually what makes a picture.
The Canon EF75-300 F4-5.6 USM
III is a good beginners' choice; it's cheap and can, if used properly, produce some great images, although it gets very soft above about 230mm.
Hope this helps.
