I got a reply from the seller:
Dear rottidog,

Greetings,
This item is currently out of stock and, unfortunately, we do not know when it will be at one of our storehouses.
The reason for putting such a high price is to prevent customers from buying it and then waiting extra time for the arrival of the package. We received complains about it earlier and since we do not want our customers to be dissatisfied, we have put this price for them to contact us first.
The regular price for this item is 630.00USD.
Please keep checking the latest information on our site MOMO, sparco items in xenonlv store on eBay!
We highly appreciate your understanding of the matter!
Best regards,
Valeria

Guess they sold out before the ad ran out & at $4000 I'm sure that would have haulted any sales

 

LOL, I have not short fueled a plane on 12 years yet, but even if a fueler mess things up the pilot should notice it before even pushing of the gate.

 

It was all about the math of the conversion back then, a learning experience. The pilot was commandeered for his flying & it was even on an episode of Mayday.
Kinda freaky when I see something on tv, a regular episode & can go: HEY that's just a lil north of here, I've been there!
