By about '74 EDI was mainly served by T3s . We on the T1/2s rarely saw EDI , 'tho we heard plenty from colleagues who ended up in the cabbage patch at the end of 13/31.
Shuttle back up at EDI from '76 was us T1 boys , and before Rwy 25 opened .. We'd always tried to pull the reverse levers back further than they were designed for.
