Yes, get a loan...
but my advice is not to spend it on training. If you are up for the challenge... buy a plane... start a flying club and let that aircraft work for you.
A few years ago, I purchased a very nice 172 for 47k. Started a flying club and flew the aircraft basically for free. I sold the aircraft for 53k.
For you, the difficult part may be learning all you can about intelligent financing, starting a club and running it efficiently. AOPA has much good advice on this subject. Also, with upward spirally cost of renting an aircraft outpacing inflation, I truly believe, shared ownership and flying clubs will become more popular. Just something to think about.
Also,,, I love being an airline pilot and would encourage you to follow your dreams regardless of the negativity on these forums.
