You know it's a prank, but that's still funny!!!

I read somewhere that they never fill jets completely with fuel because it would make the plane too heavy and cost them more money.

Try using a "single black line" instead...

The comments show how I got there...

Thanks for the info. I think we'll keep you.:))

Just an idea I had one day that proved to be pretty good.

It still took me a while to figure. I was adding image into the template rather than under and ending up with the added image vanishing. You just can't make it simple enough for some folk.:))

literally LOL

You have to check EVERYWHERE. I think it's about 13 different places you have to check on the wings. It's been a while from when I last flew, so I may be a little off.

I haven't done a real preflight since I was in Civil Air Patrol, but I remember having to check the fuel tanks for fuel and water. Oil in the engine, air in the tires, flaps, slats, mags, etc.
