Having had to give various presentations myself, I'd start with the advice given earlier, start with what you know.
You said 'I am the only one to have had a fast jet flight'
So, assuming you had to suit up, tell a story about that. Maybe in this sort of order....
a/ I went on a fast jet trip in a ****
b/ before I went up I had to attend a briefing
c/ we have to wear safety equipment, then start with a sequential list
d/ The first item you put on is clean pants, coz (1) your mum always told you to, (2)you'll be sitting on a 'Bang' seat. If you hear a 'Bang' you'll be glad you put cleans ones on.
e/. next item, brief description of what it is, why it does it, why it goes on in the sequence it does, before the next bit.
When volunteer fully suited you're ready to fly, end of demo any q's?
Perhaps an FJ driver or squipper can tell you the seqeunce of suiting up, and go from there.
Beags' audience would look something like this
