Fantastic film
The B-36 had a fairly short service life .e.g Jimmy Stewart's B-36 '5734' (51-5734) was accepted by USAF in November 1952 but sent for scrapping in 1958.
Convair flew a swept wing solely jet powered version - the B-60 - but its thick wing and low powered engines meant it was no competition to the B-52.
There was also a cargo/passenger developed the XC-99 designed to carry 100,000lb of cargo or 400 equipped troops. The USAF ordered just one,
The B-36 was deployed to the UK where one came to grief running out of fuel in transit to Fairford. The crew abandoned the aircraft which crashed in Wiltshire.
Thankfully all of the crew survived and there were no injuries on the ground.
An excellent book on the plane is Magnesium Overcast by Dennis R Jenkins - published over here by Midland Publishing..
