What I'll never forget is seeing the toutchdown marks on the taxiway!
Perfectly straddling the centrline, on the thousand foot point..... if one had been painted........
A few years ago in Dublin I saw a remarkably similar set of tyre marks on parallel taxiway, and I wondered!!
Turned out that the Aer Lingus A330 Fleet Manager had switched over the BSCU whilst taxiing and caused all wheels to lock. One of our chief guys was SNY and was not impressed. They didn't get the contract to do our training.
