Whilst there are no VC10s left to give a contrast, surely there must be some 707s? Some of those looked like they were burning coal?
Get a weekend afternoon flypast with touch and goes by a 707, 747-100 and couple of others of that era. Get all the sound and vision measuring stuff lined up and record what used to happen.
Then get the 777 and 787 along with a 330 and 340 to show where we are now.
