See post from Mercurius on the following
The Janes account of the event has now gone up online on the Janes Missiles & Rockets website, and they are accepting the airliner-contrail explanation.
Apparently the initial short section of the recording their editor had seen did look like a missile, but a longer-duration version that later emerged convinced them it was an aircraft contrail. So we must assume that the Janes opinion being quoted by newspaper accounts was based on that initial viewing and can now be dismissed.
