I think that TG and Old Fella are selling themselves short by describing themselves as "silly old buggers" with "nothing to contribute any more" simply because they are 73 and 71 respectively!
Surely they're aware that there are currently pilots in their very late sixties flying with all Australian airlines who will no doubt be pushing very hard to continue on into their 70's!
These pilots are, without a doubt, looked upon as "silly old buggers" with "nothing to contribute any more"...but they're still there!
Naturally, they are also, rightfully so, looked upon as "selfish old b*stards"!
Which is what they are! And they don't seem to know that!...how stupid is that?
And they are also unsafe
