And my answer if the question is ‘what is a half in base five?’ is 0.222… recurring (arrived at by dividing 1 by 2 using long division rules modified to base five)…..I’ve never done bases before but if you multiply 0.22222…recurring by 2 you get 0.44444…recurring which approaches 1.0 in base five
An analogous ‘problem’ in base ten is dividing 1 by 3 when you get 0.33333 …recurring…the decimal version of a ‘third’….multiplying 0.33333….recurring by 3 you get 0.99999….recurring which approaches 1.0

(Edits due to thinking it out as I go)

Simplest way, scan your pics….size them to about 850 pixels wide (about 3/4 screen width) and save in your desktop…post your message….click on the paper clip symbol and open them into ‘browse’ box from your desktop

I came across 2 photos of G-AHBU, didn’t know anything about it, ‘Googled’ and came to this website. Will upload the photos if anyone wants them and tells me how.

thawes…..do you remember how the public accessed the special enclosure for the Race Line-Up (bus , tunnel?)

Jetflap….does the original negative shed any light on the I.D. of the ‘Lincoln/Lancastrian?’ under HB-IRV’s tail….(one thought is that it’s a Rapide damaged by the clean-up software on the scans)

pagen01….Thats the Pan Am hangar under the SW CV-240 nose…the Fairey hangar survived till about 1964(http://en.wikipedia.org/wiki/History_of_London_Heathrow_Airport)
….referring to the top aerial pic the Fairey hangar is dead centre, the Queens building steelwork is at 3 o’clock, the BOAC Comet I/Hunting/Fields ‘3-bay alloy hangar’ is at 11 o’clock and the Pan Am hangar at 10 o’clock (not showing well)

Lovely images Jetflap thanks for sharing.
Is the construction in the background the new Queens Building terminal being built?
Also, is the hangar under the CV240 nose the original Faireys’ Great West hangar, or had that gone by then?

There’s a York to the left of the windsock (and a Hermes? to the right) but I mean directly under the CV-240 tail…maybe a silver Lincoln?

Under the tail of the Swissair CV-240 on RWY28R/10L (seven down)there’s what looks like a Lancastrian….I wonder whose that was?….1953 is late for that type

‘Elizabethan’ and even ‘Lizzie’ were commonly used amongst spotters at the time for the Ambassador

Good work there, Jetflap……you’re spot on with the year, 1953. It was Coronation year and the ground enclosure by the Northside control tower was expanded onto the grass between the Northern taxiway and runway 28L/10R (closed for tunnelling)…visitors were shepherded on foot across the live taxiway on which the BEA Ambassador and KLM CV-240 are seen taxying :). Airliners and military aircraft were put on display next to the enclosure ( possibly an extra effort for the Coronation celebrations….in later years when the ground enclosure moved to the Central Area there were Battle of Britain static displays of military types). For the NZ Air Race event (Oct 1953) there was a special temporary enclosure near the old Fairey hangar southeast of the Central Area steelwork and accessed via the newly opened tunnel .
The aerial shot shows the BEA fleet using the closed runway 28L/10R as an operating ramp

Now courtesy of flickr hotlinking facility we have a good photo of the DC-1 as EC-AGN before its final crash ( its on flickr at 4000 pixels :), and I suspect ‘Iberia Airlines’ in this case is an unofficial person with an excellent photo collection!)

Well done! Are the A380s still restricted to 27L/09R?
