Having trailed this across one of the spotter message boards the general view of the last paragraph is as follows:

This squadron was a cover unit used to train crews for the then secret F-117A . The purpose of this deployment appears to have been to test equipment installed on the F-117s in a European environment. These sensors appear to have been housed in the underwing pods which were quickly covered and uncovered for flight operations. When they taxied out they had pods under their wings covered with tarpaulin type material.
These covers were removed after the end-of-runway checks for take-off. These pods apparently carried the targeting equipment fitted to the F-117A's and the purpose of the deployment was to see how these would function in the European environment. The A-7D's were flown in a similar flight profile to the F-117A but of course they were not 'stealthy'. The crews flying the A-7D's were fully qualified F-117 drivers.

I don't want to die, because I don't want to end up like Anita Dobson - Frank Sidebottom, actually.
