Melvin...this is a scam. While YOU may not send the plane prior to a check clearing, others might. The scammer sends out a 100 of these offers, prints the checks (easy to do, zip cost), and waits for 10% of the suckers who actually send the plane. Cost to the scammer? Nothing. Benefit to the scammer? Anything sent by the sucker. Pure profit. While you appear to want to resist reality on this, the fact is that this is a well known, well advertised, well established scam. It is what it is.
